Apparantly Felhunters can only purge enemies now, but the Imp now has a 2 second shorter cooldown for both a defensive and offensive dispel magic. It also deals an insanely low amount of damage, perfect for breaking covered CC's (Polymorph / repentance with chills / nova / random debuff on) and undispellable CC's (Sap and Blind).
Usually I am pretty one sided in situations like this on what side I'll take (weather it is a buff or a nerf) but I've been thinking about this one. Keep in mind you wont one shot an Imp in the xpac due to higher pet healthpools / defense. If you only want to use Felhunter, it is obviously a nerf. But pulling out an imp versus things like RMP or RLS could be insane, breaking every CC except fear and hex every 6 seconds. Doubtful you can use it on your teammates or yourself if you are sapped with no magic debuffs though, would be nice if you could just for the damage.
So if you pull out an imp, you get to utilize some nice destro talents that I thought for sure I wouldn't be using. Getting instant soul fire from imp proc + instant soul fire from using a shard, could line up some massive pressure. If this change stays, I will defiantly be using an imp for Battlegrounds if I am with a healer, but I don't know about for arenas.
What do you guys think?
EDIT: Forgot a bit of a big deal. ALL dispels can be done on your target even if there is no dispelable debuff on them (to prevent healers from mashing dispel all the time). Also the tooltip is not clear on this, but it deals damage as a DoT every 2 seconds for 6 seconds, with the first tick happening as soon as it is casted. In other words, almost complete immunity to Blind, Sap, Sheep, and whatever CCs break on damage. I don't expect this part to make it through.
