I am fine with the nerfs to the damage, I agree they are overpowered at the moment. However I think Blizzard is going over board, especially with the nerf to the immune to roots ability with avatar. I would have preferred if they just lowered the amount of time that avatar was active for and taken off the increased rage regen.
Or what they could do is mark it similar to when a druid pops tree form and you become immune to sheep and hex and what not, Or atleast immune to fear.
The mobility of avatar is what made it a good talent for PVP in the first place.
Its sad but with the state things are in now, we are going to be sitting in roots for the next better part of 5.1 unless we have a paladin partner.
