Not long ago I was very happy to see mmo-champion.com post a consolidated list of all the buffs in WotLK. As a raid leader making sense of all the blue posts had become very tedious, and it helped alot as far as getting an idea of class balance issues for level 80 raiding. While it was a large step up, I found it still lacking in certain areas, mainly the ease of organization for quick answers to the question, "If I don't have x class in the raid, what other class or classes do I need to have?" As a result I have tried to lay out a format that would be helpful to me personally in this regard, and hopefully helpful to the community at large as well.

This is a work in progress and all the other classes and links will soon be added. If you don't mind taking a look and possibly giving some feedback, it would be appreciated.

Buffs shared by no other class:
Blessing of Kings (Improved Tier 1 of the Protection Tree)
Mark of the Wild (Improved Tier 1 of the Restoration Tree)
Power Word: Fortitude (Improved Tier 2 of the Discipline Tree)

The following is a list of classes needed to replace the buffs of the primary class listed:

Retribution Paladin(Total Buffs to replace: 5)

Shadow Priest or Survival Hunter
Lose: Judgment of the Wise
Gain: Vampiric Touch or Hunting Party
Note: All three buffs appear to be exactly the same.
Elemental Shaman or Assasination Rogue
Lose: Heart of the Crusader
Gain: Totem of Wrath or Master Poisoner
Note: HotC affects ALL attacks, while ToW only affects spells
Fury Warrior
Lose: Improved Blessing of Might
Gain: Battle Shout
Note: BoM is a only a Tier 2 talent, so it could theoretically be picked up by a Holy or Protection Paladin. Also, BoM is a raid buff lasting 30 minutes, while BS only lasts 2.
Moonkin
Lose: Swift Retribution
Gain: Improved Moonkin Aura
Note: Range difference.
Beast Master Hunter (Party buff only)
Lose: Sanctified Retribution

Restoration Druid
Lose: Improved Devotion Aura
Gain: Tree of Life
Note: ToL does not give the armor bonus of DA.
Discipline Priest
Lose: Blessing of Sanctuary
Gain: Grace
Note: BoS has the obvious advantage of being a 30 min raid buff while Grace will only affect the target currently being healed by the priest. Grace also does not give the added mana/rage/runic power buff.
Frost Death Knight or Warrior or Feral Druid
Lose: Judgment of the Just
Gain: Icy Touch or Infected Wounds or Thunderclap
Note: All of these buffs appear to be exactly the same.

Lose: Earth and Moon
Gain: Ebon Plaguebringer or Curse of Elements
Note: EP is 12% plus increased disease damage, EaM is a flat 13%, CoE is 10% and 165 less resistance. If you had all three you could get the best of them all, i.e. – 13% damage, improved disease damage, and 165 less resistance.

Note: Both buffs appear to be exactly the same

Feral Druid (Total Buffs to Replace 5)

Beast Master Hunter or Warlock

Warlock general abilities with very low talent point requirements to improve:

Improved Curse of Weakness and Curse of Recklessness (7 points in Affliction)
Improved Blood Pact (3 points in Demonology)

Affliction Warlock (Total buffs to replace: 2)

Discipline Priest and Mage
Lose: Fel Intelligence
Gain: Divine Spirit and Arcane Brilliance
Note: Improved Felhunter.
Unholy Death Knight or Moonkin
Lose: Improved Curse of Elements (Malediction)
Gain: Earth and Moon or Ebon Plaguebringer
Note: It may not be worth it to use Malediction for only a 3% increase over normal CoE given the DPS loss to the affliction lock putting it up.

Demonology Warlock (Total buffs to replace 1)

Discipline Priest or Mage or Elemental Shaman
Lose: Demonic Pact
Gain: Improved Divine Spirit, Focus Magic, Totem of Wrath
Note: ToW may be the best of these four.

Desuction Warlock(Total Buffs: 0)

No unique buffs, but can obviously put up any of the curses.

Similar efforts at [WotLK] Listing of class synergies (talents and skills) and Raid Stacking 101 A Dwarf Priest

Assassination Rogue - Tier 9 - Master Poisoner 3/3

Combat Rogue - Tier 9 - Blood Poisoning 2/2

Subtelty Rogue - Tier 5 - Hemorrhage 1/1

Direct equivalent of Heart of the Crusader is an Assassination Rogues Master Poisoner

Combat Rogues also get Blood Poisoning which is equivalent to an Arms Warriors Blood Frenzy

edit: urgh too slow >.<

This thread is different, because it reflects the current changes.


Other buffs not listed here are the glyphs for blessings.

Glyphed Might adds 10% of AP as spell power (might work with other spell damage buffs) and Glyphed Wisdom adds health per second equal to mana per second (unique).

Leader of the pack can be improved by talents to give heal raid members on crit, this makes LoTP slightly better than Rampage (if the druid has that talent).

Windfury (any shaman but likely supplied by enhance) is the same as the Death knight's Icy talons, providing 20% melee haste.

You might want to also mention that Grace and Blessing of Sanctuary, besides having the difference of one being a 30 minute raid buff, it also gives the mana/rage/runic power return, which is something no other class brings.

This is a different mechanic from Blessing of Sanctuary's Rage/Mana/RP regen on block/dodge/parry.

Guess I'll chip in the Warlock class.

Affliction lock (Total Buffs: 2)

Disc Priest and Mage
Lose: Int and spirit
Gain: Divine Spirit and Arcane Brilliance
Note: Int and spirit gain depends on speccing into Imp Felhunter or not.


Demonology Warlock(Total Buffs: 1/2)

Spell Damage increased buff:
Mage, Disc Priest, (Arcane)Mage, Elemental Shaman or Resto Shaman
Lose: Spellpower increase
Gain: Improved Divine Spirit, Focus Magic, Flametongue Totem, Totem of Wrath
Note:
Totem of Wrath gives 140 spell damange and 3% spellcrit for the entire raid at 70, 280 at 80.
IDS: Depends on spirit gained trough gear.
Focus Magic: Gives 150 spell dmg at lvl 80, 80 on lvl 70.
Flametongue Totem: Gives 114 spell damage and healing done(highest rank is lvl 67).
So Totem of Wrath looks to be the best.


Spell Damage taken debuff:
Moonkin Druid or Unholy Deathknight
Lose: Curse of Elements
Gain: Earth and Moon, Ebon Plaguebringer
Note: Curse of Elements gives 10% increase, 13 as affliction but affliction locks use CoA for damage instead.
Both Earth and Moon and Ebon Plaguebringer give standard 13% so these would be the better choices.

Desuction Warlock(Total Buffs: 1)
Same as above with CoE

Hope it matches the intention of the structure.
Wouldn't it be a good idea to have a list with the buffs and debuffs from best to worst for easy comparing? If yes I could make that if people want.

Edit: I saw that under Retri pala, Heart of the Crusader gives 3% crit for ALL attacks. Totem of Wrath gives ONLY spell crit. Master Poisoner gives 3% crit for ALL attacks aswell. This is asuming that the tooltip is right.

To clarify:
Totem of Wrath
Summons a Totem of Wrath with 5 health at the feet of the caster. The totem increases the damage done by spells and effects by 140 for all party and raid members, and increases the critical strike chance of spells and effects by 3% against all enemies within 40 yards. Lasts 2 min.

Heart of the Crusader
In addition to the normal effect, your Judgement spells will also increase the critical strike chance of all attacks made against that target by an additional 3%.

Master Poisoner
Increases the critical hit chance of all attacks made against any target you have poisoned by 3% and reduces the duration of all Poison effects applied to you by 50%.

Edit: The buffs and debuffs are almost all the same. There are a few differences.
Leader of the Pack vs Rampage, the Healing part.
Earth and Moon+Ebon Plaguebringer > CoE for reasons mentioned in the warlock buffs/debuffs.
Trueshot Aura has 45 yards, Unleashed Rage and Abomination's Might are 20 yards.

Totem of Wrath gives 140 spell damange and 3% spellcrit for the entire raid at 70, 280 at 80.
IDS: Depends on spirit gained trough gear. Also gives mana regen.
Focus Magic: Gives 150 spell dmg at lvl 80, 80 on lvl 70.
Flametongue Totem: Gives 114 spell damage and healing done(highest rank is lvl 67).

Improved Moonkin aura slightly better than Elemental Oath. First is an aura, 2nd is a proc on crit, will not really matter much in the end.

Improved Devotion Aura gives Armor and Healing received. Tree of Life aura does not give the armor buff.

Curse of Weakness gives a bit more Damage decrease than Demoralizing shout(unimproved) and Demoralizing Roar(Unimproved).

Ferocious Inspiration gives 3% damage increase for the entire raid, unlimited range?. Sanctified Retribution gives 2% dmg done for the entire raid in range(30 yards).

It appears to me you're overspecialising some classes:

DK - Improved Icy Touch - 3 points in Frost
Warrior - Improved Thunderclap - 8 points in Arms
Warrior - Improved Demo Shout - 8(?, been a while since I've raided) points in Fury

Improved Thunderclap is commonly taken by all specs since there is not much else.
Improved Demo Shout is taken by both dps specs commonly.
Improved Icy Touch is always gonna be taken by a deep Frost spec, regardless of dps or tank. But ith only 3 points to spend it's also likely that other that other tank specs take it.

Actually, reading the first post again you're not even looking at the improved versions ? Then it makes even less sense to me to split them into different specs.

This is a spreadsheet that I posted in some of the previous threads on this topic, hopefully it can be useful here. I've updated it with some of the new abilities and updated some pet abilities as well. I'm also very bad about catching errors, so if you see anything that needs to be fixed or any buffs/debuffs I've left out please tell me so I can fix them. Suggestions on how to make it better are also always welcome.
