Seriously, this has to be the most useless voicechat ever...
I mean, I am against voicechat in a game as toxic as LoL anyway, but what RIOT did these is just a joke.
Name one premade group that doesnt have TS, Discorde or any other of the far superior (to the ingame voicechat) communication tool running anyway.
They literally implementen Voice chat for the only case where people didnt need it and for nothing else.
Honestly, do they even think before doing stuff or are they just implementing everything without thinking about it? (Would explain some things though...)
