Add voice chat, like please, add it

I don't understand why 5 player voice communication can't be added into the game!

It would make my silver/gold games much easier to win since most of them know how to mechanically play their champs but have no sense of coordination, understanding on other ally champion's strengths and general sense of slow paced progression.

My team have thrown SO many games when our victory was assured purely because we couldn't communicate to each other what to do in the mere seconds before we predicted something would happen. And I always thought that if I was able to talk to them as a fight breaks out, we would coordinate much more effectively! And yes pings exist, but tell me, how many times do you coordinate pings AS a fight is happening? Can you tell your teammates (by typing), certain enemies have used important CDs WHILST in combat? Cause im pretty sure, after death, you don't affect the fight anymore. Hence you start pinging.

I can't type as a fight breaks out, otherwise im "trolling" and "not helping in the fight". I can't type to tell my teammates to avoid an area, since they'll be bursted down and killed faster than I can hit enter. So why cant we just get VOICE COMMUNICATION?!

2 things would actually be partially fixed by this: Toxicity and Balancing In terms of toxicity, while most people believe the game would only get more offensive, contrary to this, it would in fact make it less toxic. The fact that people are able to get away in LoL saying directly offensive messages, is because the fact that a part of your identity is being protected through chat. Voice communications strip you of this protection. It makes you more aware of what you are saying since people will remember your voice, a layer of privacy that makes you conscious of the fact that other people are listening to what you say and how you say it. AND this would make it easier to ban them as other players would know that they were being truly toxic, not just salty, justifying that one guy who is trying to explain himself.

There will always be people who wont care, people who will intentionally be toxic, that exists in any game. Even if majority of the community here is "toxic" compared to other games, this can help the issue by aforementioned reasons. And even after all that, if the person continues to be toxic, just mute them. Add features from Overwatch like "Prefer player" or "Block player". And as long as Riot provides these features, they physically cannot be put to blame, it would have been both the toxic player's fault and those who didn't ACTIVELY mute them for whatever reason. Riot gives you protection WHEN you need it the most, if you refuse to use it, your fault. Point and case.

And on the note of Overwatch, you can see how competitive it can get through solo queue! The fact that people are able to talk to each other means that they can at least come to agree or disagree on things FASTER. Likewise, if the game is being balanced around competitive, which involves 5-man communications, then why not let the players have that opportunity too? Team comps would synergise so much better and give light to a different meta!

Does this not all benefit Riot? (Of course if there are reasons that I haven't been able to find (both for and against, i want to know all sides), then please tell me cause it makes me mad that this game could be better than what it is now.)
