Well, the basic premice of my claim is that more haste doesn't do much if you don't have the mana for the entire fight
Of course, if mana is still non-issue we both agree that going arcane is still silly.

I'm fairly sure the Imp. Moonkin Aura will be nerfed (perhaps to a static cast-speed buff), but in its current form it does have a fairly significant drawback. it is absolutely sick for burst, that much is true, but in any long-duration fight mana becomes a major issue. This is especially true for Arcane and Fire in WotLK, since both will have high mana consumption to begin with.

Actually, now that we know about Fel Armor, I have doubts that there are any additional spirit changes in the works.

I keep looking at the DK frost tree and wondering if synergy between a tanking class and the not-top DPS spec is a good thing or a bad thing. 5-mans with a DK Frost tank and a frost mage would be pretty insane... But I don't know if that synergy would carry over to 10-mans or 25-mans where targets don't stay frozen for very long. And, of course, bosses don't get frozen at all.

The old T2 Netherwind Presence bonus allowed any cast under 10 seconds to be cast for free so I would pyro when it procced and would save my pom-pyro for that occasion for some burst in pvp. The proc if i remember correctly was a 10% chance on every main nuke cast. obviously this is a 5% proc and a little more unreliable and you are limited to a free fireball not pyro so the burst is going to be smaller, however, it would still be two instant casted nukes under the influence of ap/trinket and would probably still be amazing burst. we'll just have to see i guess

Frostfire really will depend on implementation, if it can sense partial resists and switch to binary spells, it would indeed be a smart nuke. With all the buffs to resist mechanics noted in DK skills, maybe there will be more fights with chromatic auras like Mother and Chromaggus. Maybe it's just an elementalist's gimmick. We'll just have to see i guess.

Most of the benefit of this would actually come from power word shield and living seed.

Living seed is a resto druid talent that makes it so our crit heals give a shield that is equal to 15% of the amount healed. So with napkin math you'll get around 70 spell damage anytime a druid lands a crit regrowth on you (regrowth has effectively a 60% crit rate). More than that with power word shield, or a healing touch or swiftmend crit.

The numbers on it are still a bit low I think but the concept is actually pretty cool and I think would be fully usable in a raid setting with you having to use mana shield.

If you honestly think moonkin aura is going to go live with a 100% haste buff for the entire group, you're very very insane.

And seriously, reprimanding blizzard on their own forums for concepts that aren't even supposed to be public? What the fuck is wrong with you?

What's the Fel Armor change?

And on Moonkin Aura, the first time I read it, I thought it said that you gain 100% of your current spell haste. Dunno why I read that. However, a flat +haste rating or even a nerfed percent could be a fairly viable buff.

Will moonkin aura be nerfed? Almost certainly.

But even if it emerges at a fraction of its present power, it's going to be very huge. A 20% haste buff on crits would still make a big difference, to pick a number out of the air. So long as the basic concept emerges, it will be very powerful even after making adjustments on numbers.

They may have to drop the basic concept.

# Fel Armor(Rank 4) - "Surrounds the caster with fel energy, increasing spell damage by up to 180 and allows 30% of your mana and health regeneration to continue while casting."
# Demon Armor(Rank 8) - "Protects the caster, increasing armor by 950, and increasing the amount of health generated through spells and effects by 20%."

Wait, what? Warlocks get mana regen as well as a damage increasing armor? GG Blizz.
