Some champions are just so badly designed they will never be balanced
They either have their number gutted to the point where their kit is useless and we don't even see them anymore (
at the moment)
Or if they have SLIGHTLY decent number, even if it's just a little bit above shit tier numbers, they are overpicked and you can't really do nothing against them unless THEY make a mistake. If they don't make any mistakes than they don't have any counter play

These champions will always go back and forth between OP and thrash, there is no in between.
