Half my games so far is still determined by inting Jungle, Toplane, Midlane and Supp.

Why I can't play alone in a 5vs5 game?

You can.

It's called being a Yi main.

This is exactly what i thought when i read that post omg

I agree, but for a different reason. You see, you play ADC. That means, you could be 102/0 and still lose.

Like someone told me to buy wards, like wth it doesn't deal damage it's practically useless.
