Why are AFKs allowed in ranked? Depressed. No fun

Seriously, played I think 5 games today, 3 of them had an AFK. 2 were 100% no show, 1 showed up at 20mins.

Lost LP, lost division, lost all hope in having any fun in this game.

Team builder plagued with bad match making.

Ranked plagued with AFK.

I think dota2 is the way to go
