Hey!

Not sure under which section to put this so I will try here.

Since aggro is based on how much damage you do I am missing a taunt skill, or modifier.
I would almost guess it is coming with the rest of the skills and modifiers on release, but I will post this in the case that it is not planned.

Without some way to temporarily take aggro from your teammates going full damage, tanks are pretty much glorified bags of meat that noone wants to beat, and the tanks main job will (how I see it) mainly be to wait for their teammates to die so they can revive them.
I can see balancing becoming a mess if a tank could constantly hold aggro, and that would be too much I think, but there should definitely be some way to take aggro off the damage dealers temporarily, in my opinion.

That was all,

Cheers
