Match making logic...
My team:
level 16, 18, 21, 21, 22.
Enemy team:
level 12, 20, 21, 30, 30
Seems to be no premades.
My genius teammates went all 10-15 deaths and this match was nothing but a waste of time. I know this match would've been winnable, if I had teammates with somewhat thinking power, but no. Better try to 1v1 that enemy laner one more time, just one more time, maybe I won't die this time. I guess I can "forgive" them little bit because of level 30 match up, but my teammates were smurfing, so I see no problem at least not-feeding (My glorious Riven "main" top laner plays Riven with fervor).
Anyways, now Riot wonders why low levels are so "toxic". Fix the match making so teams had somewhat balance in them and toxicity will drop faster and harder than Little Boy and Fat Man.
