A World of possibilities for summoners.

[Paddle]

i liked your idea of heal, tank, damage summon. but i think it would be hard to balance. they would have to be weaker than PC tanks, healers, damage. but at the same time strong enough to make them worth playing, seems like that woud be a balancing nightmare

I don't think it would be hard to balance at all. It would be like Druid for World of Warcraft.

Just an example (and I know that primals are off the list)

Carbuncle/Resto=Healer
Titan/Feral=Tanking
Shiva/Boomkin=Caster
and so on.

Just put a restriction like a 1min Cooldown for casting a summon. Would be like a Swiss army knife. Can do a little of everything but not as good.
