(Feature Idea) Tagging bad teammates instead of blocking
Honestly, blocking shouldn't even exist. You feel satisfied after a long game with a toxic teammate and finally getting to block them and hoping to not deal with them again. And then what do you know? You get them on your team again after being blocked and deja vu you lose another game. Now of course you could waste 5-10 minutes waiting before queuing or simply dodging upon seeing this person. What a waste of time! And why should you be forced to waste this time after you've blocked the person hoping to not have to deal with them again.
Why doesn't riot bring in a feature that allows us to tag people we would never want to see on our team again? I understand that it could be misused to tag smurfs you don't want to play against therefore only keep it to avoid them from being on your team. I'm sure there's many others that will agree with this suggestion.
