tank idea sort of

this is a very work going idea riot and comes from another moba type game called SMITE and in that game Ares is a tank cc similar to morg in a way but different, but his passive is what i wanted to get at and that is riot what if you made a tank like him but his passive is what im mostly talking about. his passive is for every aura item he has on he gains a amount of ability power. how ever you could make it different though on say the person gains attack damage. or something
