^ I agree that the new Role Selection system will be great, if it was in game prior to me playing League and doing bad for those games I did awful in if I wasn't forced into a role with players who would not play defense when I said play defense and I feed bad because they didn't listen, then I wouldn't be permanently suspended right now.
However the Role Selection does help, and will make sure that I could play a hell of a lot better, it still leaves open the following.
1.) Players can still be toxic and troll, Riot can do manual Audits, and add a report function this can help take care of this problem.
2.) The second problem still is bot lane players and auto locking plus players who are stubborn and don't listen for example this is a reason I feed, or do bad a lot of times players don't listen when "Play defensively" is called even at champion selection because I know the ADC sucks, but I don't be toxic I just say play defense, and then they choose to run out and auto attack all the creeps shoving lane very far. (This type of behavior just isn't something I can do good with, and a reason I hope that Riot will allow players to Duo Queue for ADC/Support together.) Because while I can't play with random players often without doing bad a lot of the time its possible for me to Queue up with a friend who thinks and plays alike and do well.
3.) The problem is while this does eliminate quite a bit of toxicity, it still doesn't fully fix things that people will get mad and rage over like.

4.) Team Compositions work with at least 2 players for the basic combo, but in order to do the higher end stuff you end the entire team working together at champion selection and to know what everyone else is doing, I am hoping that this new Role System will encourage more team-play, but this is still one of the problems that won't be resolved by the new system, for example you could get limited Team Combo's but if two other players do not want to do something and choose not to lock a specific champion or auto lock it doesn't help anyone either.
Still I like the fact Riot is going in the right direction here.
