How do i maximize my impact as mid

On any other lane i have 50+% winrate but on mid iam at 43%.

The thing is i dont feed, i get MVP 70% of the time i lose. I gank earlygame (unless i see both gold and exp lane being pushed under enemy tower).

I mostly play: luo yi(the only one with decent win rate), aurora, novaria, change, nana.
