I have mixed feelings about this one. I agree with Leon that it would just cause issues in less populated/more social rooms like a training room or a glad room. Anyone could just come in and SS or take a picture with their phone of what you're saying.

Even though it'd be cool to watch over a room like a DM for example, I see it causing too much drama. Plus it's already a thing in most of the game modes anyway once you're dead or join a room (Duel, TDM, Team Glad, etc). Only difference is your name is exposed. So it's not like you don't get to enjoy spectating at all.
