Okay, so Atrocity is gone. Good riddance. The synergy with Haunt would have been kinda cool, but what's the trouble in manually casting Corruption? Less automation is the last thing we need.
What did they put in its place? Cripple. I gotta admit I like the idea of Cripple a hell of a lot better than Atrocity. Even though Cripple in its current form is pretty overpowered I do like it in concept.
That being said I've gotta be the wet blanket you all know me to be... It really doesn't offer a whole lot in the PvE realms of things. Maybe for kiting adds. Vashj, for example would be a good use- but really it's just a beefed up version of CoEx, and in most cases CoEx is enough.
I'd like to see cripple get a cooldown attached. 30 seconds (ballpark.) In addition to the slowing effect I'd like to see it boost your damage over time effects by a percentage as well. Not too much, but enough so it would be worth more DPS than 1.5 seconds of a Shadowbolt. 10 seconds of say.... +25%? Something like that? /shrug
I just hate seeing talents with limited PvP use or limited raid use. Why can't they design everything with both in mind? The last thing we need is another Shadowfury or Dragon's Breath.
