Not sure if we're going to keep this or not. I was toying with it's cast time because there was a huge discrepancy in the Imp's regen/throughput when you a 2.0 cast time vs a 2.5. So much so that you'd you want to have a 2.5 cast time instead of the improved 2.0 because it would run OOM.

08/11/2008: Sugg. to have haste/crit affect Affliction (Source)
I think Haste and Crit benefit Affliction as is because Shadow Bolt is still a good % of your DPS output. I understand the scaling issue that Affliction had in BC where it was good in the beginning because of the lack of crit/haste on gear, then worsened as you got more crit/haste towards endgame. We'll do DPS parses and if we find it not scaling as well as other specs we'll address that.
