Thank you for banning, but there needs to be more! (Ranked)

So I've been getting notifications that the summoner that I/we have reported has been punished. This is great news, however I quit playing last season for about 8 months due mostly because of the afkers. 7 out of 10 games I had an afker which is a lot of bad luck I understand, but the new notification system gives me hope that changes are happening.

With that said I understand that people have bad games, however when a person that dies every 3mins I would have to disagree that its just a bad game. Recently I clawed my we up the ladder and now I am back at the bottom. I tried many different things including just flat out letting the other team have the first turret so I can gank with the jg to struggling lanes only to have then say "hey they killed my laner so I am going to wonder off into there jungle with 3 people mia".

Banning people that lets just say for the sake of argument lack of common sense to keep themselves alive is a bit harsh. If there was a way to ban them from ranked for 10 games if they have 10 deaths would be great! I had a game were a person died 15x in 30min and everyone on our team was basically following him around so we could at least try to save him. Did he mean to feed or was he just terrible? Personally; I really don't care either way however it should go without saying that he should not be queing for competitive play.
