Not being counted as loss when you have AFK's on your team
Its emotionally frustrating when you win lane really well, over farmed, killed your opponent 2-3 times, even killed jungler, taken down tower (did this as Nasus vs Trundle), went to bot lane and helped your team get some kills and then your mid laner who has fed and then taken your few kills as last hits, AFKS. The reason? "His parents were mad".
The rest of your team is composed to 100% noobs, not to mention a soraka who is pretty useless when she just stands there poking with her q. A trist who is missing and farming most of the time.
How is this fair game? You can try to carry this match but with their combination of Soraka, Bard, Trundle, Nocturne, and Velcoz, the CC is wayy too high to try to 1 v 5.
