The most annoying thing about ranked.
I hate when you're in champ select, and everyone calls what they'd prefer to play, and some genius who has "pick order" picks away someones preference, then completely loses the game with that role. :@ I know pick order is there for a reason but I hate it. I always let people have what they want and try to fill. In this instance I was duoing with a friend who mains ADC, so I wanted to support him. Some genius took support away from me and ended up doing so poorly there was nothing any of us could do. I was getting /msg messages from my buddy saying this support didn't ult during fights, and wouldn't even use his spells properly. Grr >:
