Can someone at Riot please look at my account?

Look, i'm a casual player I barely get any time to play.

If iron/bronze/silver is so common then why do 90% of my normal matches have at least 3 plats in it.

And for some unfathomable reason they're always on the opposite team!

And i've seen them absolutely destroy the lower elos can someone explain to me whats competitive about that? Its like godzilla crushing tokyo.
