Potential un-banning of accounts with strict probationary period.
I think there needs to be more in depth research done into each case of bans. I know there are millions of players worldwide, but I find it ridiculous how quick punishment is given out to people for situations like this. I've gamed my entire life and never have I run into a system that is so quick to punish yet so unwilling to compromise with their bans. In fact, I've never been banned in any other game I play. I just hope that one day your system will lift bans and give players one more chance on their accounts that have helped Riot remain so profitable. Without people paying money for skins and what-not, Riot couldn't exist, so I really think there needs to be a certain time-frame given to accounts that have been banned to where they'll be given at least a chance to redeem themselves.
Even if it's a couple of years before the account is un-banned, there should be something in place. Then, put that account on a very strict probationary period until they have demonstrated that they can be a positive influence on the game. Do you have anything like that in the works? If not, why not give it a shot? It's a win-win for Riot if you were to do this. If you give people back their main accounts that they've potentially put hundreds of dollars into, they will be more likely to put more money into the account and be on their best behavior. Worst case scenario, they rage once and you can just ban them again. I really think you need to look into something like this because it's a win-win for all parties involved.
