We spend a lot of time customizing our character, only to see its face occasionally. I propose there be another action (e.g. Wave, Sit etc.) to remove your helmet, for a short period of time. That way we are able to see our character's face just a bit more often and to display to our friends. Any thoughts?
Our Guardians got plenty of face time in the tower, and you'd be surprised how much time you can spend there with your fireteam inbetween adventures. There's also the two concerns of being able to take your helmet off in locations where you shouldn't be removing your helmet (space) and the fluidness of the emote ending should you end it prematurely when you come under attack.
