Queuing for ranked without doing your best to win needs to be made unacceptable behavior
I'm getting really sick of encountering players who claim that 'they're tilted and probably going to lose,' and then proceed to do something almost indistinguishable for intentionally feeding. This happens constantly, and there's no punishment because 'lol just a bad game.'
Ranked needs to be held to higher standards. Players who join ranked games and claim that they're going to lose because they're playing badly should not be able to queue for ranked. This behavior should be considered unacceptable and has no place in ranked.
