Why are the things that we hate still in the game?

Riot obviously has to know that we hate this high damage snowball meta and they do nothing to make it less toxic. They add more damage and more rng into the game. I honestly think that the game was better when people had time to react to things. If somebody outplayed you it hurt more but also if you outplayed somebody it felt rewarding. Now I don't get that feeling, somebody kills me and it just feels like a stat check "he had more damage, so he killed me, w/e". Remember how you had to dodge like a god? Now somebody kills you before you get the chance to do that. Hiding in a bush and waiting to oneshot somebody is rewarded because it is possible to kill somebody with a single combo. That is not a healthy game design. When cheesy strategy is the best strategy in the game you know that something is not right. When the simpliest strategy is the best strategy in the game you know that something is not right. How did oneshoting somebody become the main thing when you want to beat that person? At this point the old marksman have the healthiest gameplay, even tho I hated them before, because they have to actually aa you a few times before killing you. But then there are some Marksman that just press buttons like casters and they are still played as adc. W/e I guess.
