"#1 reason Yasuo is banned"
You are all bronze elite who have never tried to play him or when you did got roflstomped. You have no clue what the champion does or you would know how to counter him. You charge the duelist slayer into constant 1v1s instead of teaming him. You go at him with squishies which he counters and then die. You keep the same build pattern in every game hoping no one challenges your idea that a single build will counter everything in game. None of you buy armor. None of you poke him into submission. None of you play champions that counter him. The truth hurts, but y'all just suck.
