he's a bit too strong currently. I don't know if it's fair to say he will destroy any melee lane matchup. I've seen yorick kind of being a good answer to urgot and maybe mordekai as well. Makes ganks difficult especially if you are a squishy jungler as well.
Urgot's pretty OP in low-mid elo (not sure about high elo) since people heavily underestimate him. He's not a troll pick, he was reworked a while ago, and his rework makes him a pretty good Juggernaut
