Just wondering if anyone has done any theorycrafting on spell haste rating and where it will fit in with item budgeting. From the items I've seen so far, a good deal of caster items found in Black Temple have spell haste rating on them, but I personally only see the benefit for dps casters. Items like Bracers of Renewed Life lead me to believe Blizzard thinks spell haste will be good enough for healers to sacrifice mp/5 for.

Will spell haste be primarily a situational stat for healers, switching it in when quicker heals are appropriate? Or will a faster heal allow for enough regen time to sacrifice mp/5 for?

On paper, I personally think spell haste, as a healer, doesn't seem attractive enough to give up mp/5 and +healing for.

On the caster dps side of things, how attractive is spell haste for mages and warlocks?

The PTR notes mention that the haste rating was nerfed to provide less benefit per rating point, but I haven't found any actual data regarding how the formula was changed.

For shadow bolt, 1 spell haste is better than 1 spell damage in terms of dps. It does also increase mana per second though.
However, for affliction as most of the spells are 1.5speed it isn't very effective due to global cooldown.

I used my spreadsheet, warlock.xlsx (sorry excel 07), for calculations. Borrows heavily from other spreadsheets but might have made some errors somewhere. (21 haste rating = 1% spell haste?)

excel 03 compatiable but untested.

As for healers, it means more time in 5sr and more hps but haven't done any actual numbers on it though.

Hmmm, good point.
I forgot about that.

Is a 1% speed increase calculated before or after cast speed reduction talents?

After.
(otherwise heroism would make shadowbolt 2.5-(3*0.3) = 1.6s cast speed and not the 1.75s that it is.)

Pretty sure new 2.1 spell haste conversion is 20 spell haste = 1%

Edit: Quick test i did: Quag's eye procced (320 haste rating) on PTR, made my Teleport spell (10 seconds long) take 8.4 seconds, which seems to confirm that conversion

Afaik the haste formula is:
Talented Casting Time/(1+Haste)

On Live, haste rating conversion is 10.5 rating=1% haste. (QE grants 30.44% haste)
For example my talented SF with QE proc:
3/1.3044= 2.3 sec
Crit proc:
2.5/1.3044=1.92 sec
Same on Wrath: 1.15sec and 0.767sec on critproc

On PTR:
SF: 2,6 sec normal and 2.17 sec on critproc.
Wrath: 1.3 sec normal and 0.868 sec on critproc.

Assuming same formula the new rating conversion is 20.8 rating=1% haste (QE grants 15.38% haste)

Nice nerf. 2080 rating needed for 100% haste aka 50% casting time.

 

Trueth

In theory, healers could use spell haste rating to maximize downranking. More haste = faster big heals. But, unless items start popping up with an interesting blend of +healing, mana/5 and spell haste, I am not sure it would be worth it.

Of course, the value is completely dependant on your class and heal speed.

Spell haste + spellsurge could end up becoming a nifty combo.

I have Excel 2003, and I would have to download a 27 meg compatibility pack to view/edit the file (the pack works with Office 2000 and XP as well).

So it is somewhat compatiable with lower versions.

In my opinion spell haste is amazing for PvP healing. I still use the BWL paladin trinket for arenas. Seeing as the linked item is crafted, even if it isn't popular for raiding, I'd see this as a big money maker for raid guilds, and/or a huge cause for complaint from non-raiding PvPers (my assumption here is Heart of Darkness is a raid drop).

 

niska

I have doubts that one can accrue enough spell haste rating to make a noticeable difference in cast time. The classes that benefit most from it (healers, mages) have other itemization concerns that trump it in most cases, let alone the mana issues it brings up. Melee haste seems much more appealing. Wake me up when it speeds up dots btw.

 

glor

Second what Niska said, for mage PvE at least. With Arcane Blast to dump excess mana, speeding up cast time doesn't seem to be that useful as a mage. DPM can almost be converted directly into DPS. Perhaps in encounters with constant motion (aka. difficult to maintain the AB debuff), spell haste would be a more effective mana dump.

28 rating from Living Earth Bindings ( ttp://www.wowhead.com/?item=32577 )
37 rating from Naturalist's Preserving Cinch ( http://www.wowhead.com/?item=32258 )
31 rating from Ring of Ancient Knowledge ( http://www.wowhead.com/?item=32527 )
38 rating from Mantle of Nimble Thought ( http://www.wowhead.com/?item=32587 )
you could pick up as a healer (eg. a shaman).

134 rating = 6.44% increased casting speed, making your chainheal & healing wave an 2.33s cast (with 4 pc t5 you hit 2.2s).

What you have to lose for it? Comparing to updated tier 5 items and equivalents, it's

+21 stam
-5 int
-58 healing
-30 mp5

30 mp5 is alot, but a lose of -0.17s casting time is very good, increasing the hps of the shaman's slower heals by over 6% and make them more competive to the paladin's ones and boost them far away from priests whose are still healing with 2.5 gh (if not picking spell haste theirselves, of course ).

If i have to chose, i would pick hase rating. Manaregen is not that big issue while chainchuggind with alchemist stone, fixed manatide and a shadow priest or some spellsurge user in your group.

But you need a good connection to really profit from this reduced casting time, with <150ms you should really think about it, if it's worthy.

Spell haste rating is not anymore better than +dmg after 2.1 patch.

for affliction lock 1 spell haste = 0.40 spell damage
for demo lock 1 spell haste = 0.66 spell damage
for destro lock 1 spell haste = 0.53 spell damage
