Consider the fact that recently the servers were in a , let's say "questionable state" . Ofc afk is unacceptable but it so happened to me that I was constantly disconnecting and failing to reconnect ( i play since season 1 I know the reconnect drill by heart trust me ) , now tell me should I be punished for this ? I believe not but people in this named game felt like they should report me . I told them what happened , they didn't care .
So now tell me , should I be banned let's say for a week , considering that I never afk / troll / leave games ( normal or ranked ) ?
See where I am going with this ? Legit vs Non-legit player punishment argument right there .
Server issue are always a special problem. Riot gave loss forgiven for server issues before.
The times I loose because of a leaver are about 30 times more common than games that are lost because of my connection.
And I'm talking about my laptop which has not the best wlan.
Playing with my desktop I play hundreds of games without DC'ing.
A legit player should draw MUCH, MUCH more benefit from such a punishment then before.
