I don't know man, they seem a little op apart from maybe healing aura.. it sounds like the druid's tranquility from WoW, but again I must say with mass healing already having a tick and able to be spammed it would have to offer something different wouldn't it.
Stoneform on a warrior sounds like a good shout too but instead of giving outright immunity it could increase ac/amc for 90sec and decrease dc and accuracy for 120sec or something , with no hp regen --- edit: just realised protection field exists, maybe stoneform could increase all defences for 90sec, just a thought.
I really hope taos get some aoe attacks rather than more support spells. We have to swap spells on the fly as it is!
The stone spell for war is basically a support/tank spell. Allows the war to run in lion roar then turn to stone becoming 0dc tank for 10secs. Somebody could be about to die on a hunt, war lion roars and stones himself allowing the people struggling to compose themselves whilst war is being a tank.
