People do realize that. What you're not realizing is:
"You will always get bad players"
Top laners chain feeding because they won't play back for a bit can't be avoided with voice chat.
Players being asked to build items their champion scales with and them responding with "Fuck you", isn't something that can all be avoided with voice chat.
Players ignoring the chat requests and pings for assistance at Baron that they already receive because they want to slap minions bot lane is not going to be fixed by voice chat just because it is voice.
Players harassing you for not building X item because they don't realize there are useful items outside of their mobafire guide is not going to be fixed by voice chat.
"you will always get people who dontr belong in the elo your in'
They are not going to suddenly learn to use their champions better just because there is voice chat.
"you will always get trolls"
Someone having a temper tantrum like a child and running down mid because of the support's champion pick isn't going to not do that because of voice chat.
but this can all be NOT avoided with voice chat. In some cases, it's going to be made worse,
with voice chat people can hear u and regardless if they want to ignore u or not u can tell them what ur intentions are and can work around that
You are not realizing that people are already told others' intentions and they don't work around that anyway.
But the number one thing you don't realize:
There are already twenty different voice solutions out there for online gaming and all the people who want to use voice chat for League, already use one while the others do not exercise that option; They opt out, not wanting to get yelled at by raging, teenage children.
Well, except you want voice chat, so I guess it was actually the number two thing because you can get voice chat yourself.
also im almost 80 percent sure that people are less likely to be toxic on voice coms when they can hear the other people talking back to them
I see you've never played on Xbox Live.
