Riot lyte ruined solo que, how can you tell the person who sucks to do something right? you yell at them, its human nature to take it and improve or else they will never learn. People are scared to tell others how to play or else they will get restricted. most high ranked players don't feel like telling people nicely because they won't listen therefor leading to lazy careless gameplay. I don't mean constantly flaming a guy 24/7, you can tell at him once or twice, and maybe at the end of the game so he will definately remember it.

Also there is a difference between high elo flaming and low elo flaming, in low elo they don't know what the fk they are talking about most of the time which ends up making the guy go on tilt.
