I'll do instances, will I be able to run through them, kill mobs and do damage the same time? I guess no and thats the point.
I just want some1 to heal my babies, while they are in combat killing some mobs. Btw. with 4 shamans healing each other, I'll need 16 macros/keys (complete numpad). Plus one for tank healing. With 1 heal shaman I'll have only 5 keys for healing.
