High Elo players matched against low elo in normal games

I know normal games are for having fun and for practicing champions and trying new builds, but it is just so annoying when you face diamond players as a low elo player. I have almost every game platinums and diamonds in enemy team and it is just pissing me off when they wreck the shit out of my team. Riot should make same system to normals as rankeds, You cant join low division games as platinum, diamond etc...
