What champions do you hate playing/ laning against ?
For me it's Vayne, this champion is pure aids since forever, I just can't stand even the look of her, also you stomp her in lane and once she reaches her 2 items power spike she becomes literally 1v9. Her kit is overloaded for a champion that should be a late game hyper carry, that has a good/ mediocre early game, that can't be itemized against.
