Galio
Galio in my opinion of overloaded. He just needs to bring AfterShock and he is unkillable which wouldnt really be too much of an issue. But while he takes that key stone all he does is build a RoA and he also just does an insane amount of damage. After shock and his w just make him way to tanky and if you even want to get into lane he just q's you and u just lose so much health. Besides him being tanky his cc also makes is hard to even doing anything while he just is pressing q and his empowered auto just killing you on the spot. I think his damage needs to be nerfed so he can go back to being a normal tank.
