With all the pruning going around it baffles me that this ability still exist. Blizzard get's rid of a core Arm Warrior staple like Overpower (which will come back as a talent in Legion) everyone begged to have it back during WoDs beta but to no avail. It was just that ability that said screw you to Rogues and always crit, consistent like that.
Now I remember first getting Slam during Vanilla WoW and I thought it was a joke. I have to stand still and cast it? Wha? So I thought it would at least hit super hard....it didn't. I'll admit during WoTLK it was kind of interesting weaving them into your rotation while timing your white hits, but it was never an ability any of us liked. Since WoTLK the damn spell goes through some dramatic change each xpac, as if Blizz is trying to make it work.
Why don't you prune that crap and just let us keep freakin Overpower!!! The only frustrating thing about the pruning is it's as if the people working on the class really do not play that class at all.
