Cataclysm Changes: Warlock

[Mosg2]

I haven't seen any quotes indicating cooldowns on shard usage. I'm not saying that there won't be--Just that so far things look good.

I pve, I think I'd easily get 2each/boss fight.

will not be able to gain additional shards during combat

I think not lol.

Also, there would have to be a cooldown, come on, they still balance PvP, and 3 instant soulfires at will would pretty much negate all 2v2 combat lol. 2 warlocks would simply take a target each and win :P I read somewhere ( I think a blue tracker on wowhead or mmo-champion, but I'm at work and cant look them up right now) that at LEAST a 20s cooldown would be implemented. This makes sense, as a good boss fight lasts longer than 60seconds, and you would have to pick and choose when to use them.
