Sylas ult is bad champion design

Sylas ult should never have been put into the game. Riot was too busy thinking about what would be cool, instead of the tools in the kit that can be used for balancing. Sylas ult is RNG, it changes drastically every match with different opponents. You can't balance an ultimate that has over a hundred completely different effects depending on team comps. There is just no way to ever make that balanced, especially for something like solo queue where nobody thinks about team comp.
