Master Yi isn't broken, funneling is and towers are.

Seriously, how come every time this strategy is used the game becomes way more boring than it is. All you do as the person against it top, is just leave your tower so that they only take tower and not get a tower and kill. You have to fall drastically behind while they're getting ahead regardless. It's literally just an unfair strategy.

I'd actually be open to hearing strategies that beat it besides letting them funnel and soaking as much xp and gold as you can before having to run away to prevent being killed under tower.

Towers seriously need to be stronger and funneling should seriously not be a strategy with it's only counter being "let the enemy team funnel and don't contest it."

EDIT: Guess I should have named the really big villain here. The items, they synergize too well with his kit. Surprise, most champions who build those items are also broken. Yi hasn't been a problem in previous seasons, and now all of the sudden he's a problem again. It's seriously the items and how easy it is for Yi to actually dive people because of how bad towers are.
