Gnar ult
I started playing Gnar recently and I really liked his kit and he matches my playstyle. But i really have a problem with his ult and passive. I think Riot should make his ult become a mini Gnar/Mega Gnar form change. So you could do like Nidalee, Jayce or Elyse. This could really make him a viable champion and he could be played in competitive scene. Now he just does not fill any meta.
I might make mistakes sorry for my english.
