Ornn is fine

Seems fine to me. He's not that mobile, has easy to dodge/predict skill shots, and he's melee ranged. His strength is his utility ultimate and his ability to have your team out scale the opponent's team via extra upgrades to core items. In the middle of a fight I don't find Ornn as useful as many other front-liners. I imagine he's not fun to lane against though.

Unstoppable by the way- Oh, wrong place in time. It's totally not like removing that made it easier for people to handle him. He's a tank that is also a lane bully, that's the point of his W. Nerf W and watch him fall like a domino.
