As to the Druid tank thing, I'm not to the point where I have lacerate yet and a Warrior can hold aggro better than me, AND I'm mostly rest spec, but I have found myself tanking dungeons more than anything lately. I tanked and healed for ST and BRD, but mostly tanked. Normally I'm pulled in as just the Druid, to do whatever, but then they ask and my stats actually outweight their intended tank.

Higher armor than some paladins my level, with 4k health. With buffs I get to near 8k armor, but I really rely on taunt and feral charge for aggro control.
Meanwhile, most of my good stuff is for healing.

But I feel a full fledged holy priest would be better than me. I just end up doing both jobs due to a lack of Warriors and a lack of holy priests.
Preferabbly, I'd love to be catform as I can do the most as the wild card in a group. DPS in catform and shift to help heal or to bear form and grab aggro. I feel like a wipe saver in catform, as I can adjust to a problematic situation more easily.
