YEs and No, all accepted except powers, he can take peoples powers AND becomes stronger? That just is OP

agreed, being able to shape shift and mimic voice is a pretty sweet power in it's own right. 
I'm not really one to talk since I gave my own characters pretty powerful powers myself.

The difference however is that my character's both have serious limits to what they will do.
Weiss can fulfill wishes so that's pretty damn powerful. But he can't fulfill his own and needs a wisher to sign a contract.
Heravix isn't so much limited as he'll never have any motives to do anything drastic. He won't use any magic unless it serves the plot or saves a life.
