Getting flamed for losing lane to platinum players.

Every game its the same damn story. I'm either crushing someone around my same "mmr." Or spend 20-30 minutes getting flamed for losing lane to someone thats impossible for someone around my skill level to beat because riot thinks that platinum 5 vs silver 4 is an even matchup. It mostly happens in normals instead of ranked. I know people on the boards don't give a shit if its normals but i know for a fact they don't want people going to ranked to play casually.

But with every game I'm getting pushed closer and closer to playing ranked for fun if only just because it's the only place where the matches are close to even.
