i think the group hot should be on a recast timer and castable in combat, to compete with friars. theres no real style procs or effects and no stuns, leaves the class a little underpowered with almost every build
also the whe you shift from one type to another theres a spell affect lag, id say about 5-6 seconds long, so theres no "o shit im going to die better switch to treant mode to heal" or " need to taunt so switch to golem mode"
