The problem with yasuo and zed
You need to have a good team comp that works with them and also an enemy team that doesnt completly shut you down and there are ALOT of champions that can counter a zed and yasuo with a simple click of a key. They are constantly banned and hated by the community because in the case you actualy able to pick them and your team actualy builds a comp around you they are realy OP but that rarely happens.
Every game and I mean EVERY GAME I always suffer because either Im first pick and get countered, my jungler and top dont want to play any of the infamous AP champions for their role and because they are so commonly banned that every game my fingers are crossed.
