I kinda can't help but upvote. This has traditionally been my gripe with leegs for a long time.
I can do extremely well, stay cool-headed, support team, make plays, for several games in a row and lose them all because teams are just too damn heavy. Too heavy. My last game (admittedly I didn't do spectacular) my yi was just so immensely heavy that every single time we got a break (aced enemy team, killed key enemies), he just went and died. He stayed apart from team as often as he possibly could, went 1v4/5 fights several times, and was just probably just one of the worst players I've ever seen.
Now I get it, I'm in silver and new players are going to happen.... why aren't they happening like that on the enemy team? I mean their entire team was at least able to not feed. Their team was well rounded and overall really decent. I had at least two players on my team that felt brand new to the game.
So idk. I don't know what to do sometimes tbh. I play pretty well most the time and I've felt that my experience and ability would at least help me climb to an above average status but apparently, after five years of playing this game, I'm just as good as a brand new player.
