PSA Don't take someone's role without their permission

Just had someone straight up take my lane in ranked (he didn't even ask)

Apparently he was on a long win streak as Alistar Support, and thought he could continue it by stealing Support from me.

Ironically, he fed horribly while I beat Trundle top :P

We still lost though...

I don't care how good you are, unless the person EXPLICITLY says "Yes"...Do not take their role
