I play 2s on an hpala with an enchancement shaman and i really enjoy it when the teams we play against are usually any combination of resto druid. i recently saw a rogue's life jump from 20k to around 90k in about 2-3 jumps. His partner was a resto druid and its wierd when i didnt see him casting at all.
One preferable nerf is lifebloom activates when purged. ( not sure if this is what blizz intended, but imo too op)
another is the fact that resto's seem to be able to heal better when around 2k mana instead of full. ( sounds impossible, but its not)
