Account Blocking Effects
I personally really think that blocking a player should also keep you from playing with that person again. Currently blocking players only hides their chat messages which is okay but it doesn't really keep that previously toxic player out of your experience. It's really just my two cents but I don't think anyone would enjoy being matched again with a toxic player who they had played with previously, keeping the player out of one's game play after blocking them is just a quality of life thing to me that would be appreciated if riot took that extra step. I suppose if it's too complicated to change around the matchmaking system a bit would be fair then why not?
