What if its not a druid healer?
then (if he's with a paladin) he has freedom, good luck getting that off consistently with dispel resistance and fodder when you can barely spare a global to do anything but heal
I agree that the low cooldown on Charge is really excessive and I'm expecting a nerf on it soon (it really is just too good at 12 seconds), but you are completely wrong on the overpower and pummel sharing a cooldown. Overpower is one of our main sources of putting up damage. Can't just take that away from us.
Our burst is capable of being very good, it just takes time to set it up, unlike most other damage classes.
Taste for blood shouldn't be able to proc as often as it is. And 12s cd charge that guarantees ms crit is pretty dumb.
