I think the default binds for the comm wheel need to be changed. Of all of my 8 IRL friends and I who got the beta, I was the only one who knew about the comm wheel after over a week of playing with them.
No one is going to randomly try pressing period or comma in an FPS game, it just doesn't seem like a key that would ever be bound to anything.
Most people I know do not check the keybind menu to learn the controls, they just figure out the controls by playing. Without any kind of on-screen prompt, I feel like the chat wheel goes entirely unnoticed.
Like don't get me wrong the addition of a chat wheel for calling to teammates is amazing and I had been wanting something like this in CSGO for ages. I just think its use could be encouraged a bit more so that new players actually know its there.
EDIT: Also an end of game teammate review would be nice. Similar to the commendation system in CSGO. As in it would be cool to commend your teammates for exceptional game sense, aim, or communication. This rating would be translated into a trust factor system similar to CSGO's. Where players with high trust factor are placed together in games. So players with high ratings of communication are more likely to be placed in games with other highly rated players in terms of communication. So not entirely separating the queue but perhaps prioritizing the queue to give a bit of separation between casual players and the sweaty players.
