TLDR; Let's say you're Pheonix and u wanna flash. If for some reason, you want to use the comms wheel to tell others that you are about to flash, you can't as of now. How about adding that.

Longer version: I find the agent's voice cool when sending info.
IMO saying "Greetings" in Omen's voice is way cooler than typing 'hi' or saying it in my human voice. (/s). But you can use the wheel for actual info like rotating or telling others to walk (keep quiet).

I use the voice all the time in unrated and spike rush matches when not a lot is at stake. Or you would want to avoid the toxicity and chat war. The one where kids keep shouting when you are already trying your best. Also doesn't reveal race-related info so that's a plus.

At present, I can send info most of the game without talking (in unrated, ofc will talk in comp) but having an option to say that you're about to use your Q or E would be helpful. Thanks.
