You know, I've quit every single competitive video game where I was forced to talk to my allies in order to rank up.
I do not enjoy talking to random people who's only point of interest in common with me is that we happen to play the same video game. I've quit every MMO I tried to play for the same reason, because eventually I will try to join a guild and come to the discovery that the vast majority of the people on the other side are completely insufferable mouth breathing fuckwits.
The fact that I can only communicate to people through text is what keeps me playing this game. It's no different here, the odd time that I've actually joined a call to group with people, I can stand maybe 2 games in a row, then I make some excuse to leave and just block all the players because they're all... Fucking... Asshats.
I LIKE that I don't have to talk to shit fuckers in order to play the game and I am actually completely on board with Riot never implementing in game chat. It would kill the game I love.
And it's why I FUCKING HATE this dynamic q bullshit as much as I do.
