If you take away dynamic queue, people will still use voice chat
I know it feels unfair for a solo player to be up against a group of people. I think the biggest reason for this is voice chat. If you have a group of players using voice chat, and no one on your team is doing it you'll obviously be at a disadvantage due to the lack of communication. And yes, I know it sucks when other people on your team are communicating on voice chat and don't communicate you (assuming you're not in the chat). But even if dynamic queue is taken away, people are still going to use voice chat. They've been doing it long before dynamic queue and they will continue to do so. In order to fix the problem we need to encourage better communication between teammates, regardless of whether they're using voice chat or not.
