Although he still is really good, don't know why he is listed as a poor pick in all roles. His base damages are decent and he has 3 forms of aoe cc. Wall dash too.
But he isn't really shining any where, let alone being a 'viable' pick.
Old gragas ult was a LOT easier to land and his old W that gave damage reduction for longer made him more viable vs burst mages mid.
Used to love this champ, and doing well in support with him but not sure what else can be done with him.
