League Of Legends Meta Disappointment

My experience with League of Legends has become quite disappointing. I started playing in Season 3, when each character had unique mobility, but the current meta is the most nonsensical I have ever encountered. If you want to rank up in the competitive system, just pick a tank or off-tank. Minions and kills don't matter; the game just needs to drag on, and you'll win regardless. No matter how hard the opposing team tries, it feels futile.
While I have noticed bugs in the game before, it was still enjoyable for me. Now, however, it has turned into a massive pile of garbage. I hope the developers can address these issues and improve the overall gaming experience. Thank you.
