Any cool champion ideas?

So I had the Idea of a champion that can see wards, shroom's, Players In bush edc, in a close range of the player, as a passive. then as an ult it can show whole map for 15 seconds to teammates.

Q Call the Pack Place Ward wolf that can attack players ( Like Shakos "Jack in the box" ) W Howl Short range burst Slowing/Fear all in path of the attack E PounceJumps on enemy units like Pantheon or fizz R Eye of the wild Whole map viewed by all teammates for set amount of time.

^probably be wolf champion

You think that would be too Over powered? It would stop allot of gank's.
