If you intend to play WW, ban Leblanc.
She can use her clone passive as a shield to block your ult for anyone on the map.
I don't even know why that's allowed to be a thing. It happened to me like 13 times in a single game. Think I'm going to gank bot lane? JK a wild Leblanc clone appears in front of Jhin and blocks my ulti and I sit there like an idiot stunned because the clone disappears and I'm just sitting there swiping at nothing :)
So fair :))))))))
