No impending nerf for affliction (that's basically a buff in itself!)

I don't think either haste not crit qualify as an "exploit." That word implies you are somehow abusing mechanics so bad that you risk some kind of punitive reaction on our part. Usually if we don't like how a class is working we'll just fix the mechanics and not blame players for it.

In any case, haste provided a huge damage boost and was hard to fix. Crit provides a moderate damage boost and is hard to fix. So we probably won't be changing the way rolling crit works any time soon. You can use it without fear of ramifications from us.

This is referring to rolling crit on corruption and shadow word pain, particularly when involving Nevermelt Ice Crystal's 30% boost to either spell for the full duration of a fight. So, looks like no plans to change crit rolling any time soon... however, it was commented before 3.3 went live that haste rolling was difficult to fix and there was no plan to do so, and then it took them barely 24 hours to hotfix it.

It's a huge boost, and it's an unfair one in all honesty, but it's also one we get to keep, so hooray regardless.

The thing that'll keep Blizzard from spending man hours fixing it, right now? It's not making affliction or shadow overpowered, neither is exactly blowing away the meters even using NMIC. And, as unbelievable as NMIC is compared to equal and slightly higher ilevel  trinkets, it's only marginally ahead of ICC trinkets, and it's actually surpassed by heroic ICC trinkets, so it's also not taking us to heights that would have been unattainable without the bug, it's just taking us there with one 5 man trinket, when most classes need at least nonheroic ToC/ICC to get there.

I'm sure it'll get fixed eventually, 4.0 pretty likely, but I also think that as long as rolling crit isn't being responsible for 20+k parses it'll basically fly below the radar. Consider that even with rolling crit, Blizzard feels affliction is lower than they want it, so fixing it will only necessitate more buffs anyway.
