If you can't play at least two roles relatively decently, don't queue up for ranked. Period.

You can gripe about dynamic queue, I get it.

You can hate the balance of the game currently, I get it.

You can be frustrated with previous ranked games, I get it.

But this champ select system gives you the option of playing the two roles you're best at. In previous seasons, you could be forced to play 1 of 5 roles, this season you get 1 of 2. There's no reason you should be playing 1 role only and then be complete garbage at everything else. If that's the case, please take the time to get decent on easy champions for whatever role will be your secondary. This way you can play safe and not feed. Don't pick really difficult shit for a lane you don't play, feed, flame your team, get called out for being garbage then turn around and blame the system.

I know there's no way Riot can realistically get these players out of ranked but dammit, being good at two roles isn't that hard. Shit.
