i've been noticing lately that players are queueing up for ranked and then not doing anything

its normally the adc players, ranked match starts and they just sit in lane. They don't die, they don't group, they farm up till all the turrets are gone. Then they finally start trying to play.

after your team catches a fat defeat you look at the damage dealt and the only people they out damaged were the supports.

what the hell is going on
