Why do these champions exist?

Champions like Master Yi, Yasuo and Tryndamere where the only efficient counterplay is "hope they fuck up". I won't say "just CC him" because that counters every champion in the game but for these three champions they have no other proper counterplay other than "hope they fuck up".

The only reason why Master Yi's counterplay is "hope he fucks up" is because, you can camp him all game and put him like 0/10 at 15 minutes but he still puts your team on a ticking timebomb because even if he is 0/10 or 10/0, as soon as he finishes Bloodrazor + Rageblade your team is done. He will destroy your squishies and tanks singlehandedly and it doesn't matter what score he has. Just the fact that a jungler champion can play PvE all game and become carry mode without doing anything is toxic for this game.

Why Tryndamere can ult while hard CC'ed, I have no fucking clue but that needs to be changed. Allowing a champion to use a death immunity ultimate while hard CC'ed is pathetic. I have seen Tryndamere's use Q + Flash into 4 people and then crits down the ADC instantly and uses R and then Q's away. If Tryndamere can use a death immunity ult while hard CC'ed, allow Kayle and Aatrox to use their ultimates while hard CC'ed also.

And Yasuo is a complete joke a champion in this game. He has the most overloaded kit out of these three with two passives. All he needs to do is build PD + IE and take Conqueror and then he destroys your team while you can't react because Rito thinks it's a good idea for a melee fighter to have a better Braum shield. Can't damage him properly because he gets shield for free at level 18. His only counterplay is hope he uses ult or E's in a stupid place.

Remove these three toxic champions. They ruin this game.
