Why do mages, one of the strongest classes already, get an item that is not only gives the best active in the game, but also provides plenty of AP, CDR, armor and very useful components. All that isn't enough, because for some weird reason you can actually gain a shield and heal while you are in zhonya's. Like wtf is that? Why doesn't damage go through, but healing and shielding does?? That should definitely be removed imo..
