This is what I think
A: Fullheal needs a longer CD I was thinking around 45-60, as we all saw in the pvp tourney the skill is just so powerful and way to easy to get off in fights. Yes this is THE main healing class on the server but it should not be able to spam full heals left and right.
B: I think healer wise we need to look at the resurrection cool downs, players stack classes like paladin, BM, cleric, Druid on a team because 3 low cooldown resurrections are just so devastating. I suggest to bring the cool down to 5 minutes all around so that players actually need to play smart.
