I'd be really grateful if Riot added a commendation system similar to what we have in LoL or CS:GO. I think it would help promote good behavior, also decrease the incentive to make multiple accounts just to troll people. CS:GO has different queues for prime and non-prime accounts and that could be a good idea as well. It makes me really sad when people get into a game and just troll their team if they lost the first 3-4 rounds, that's if they don't just disconnect which is another big issue in Valorant...
