Is it just a small portion of the player base? Without voice chat options it would certainly be useful in grouped combat when I don't always have the time to look at the chatbox and a pop up reminder that people are talking would be great.
To chat bubbles for RP, even if I have trouble finding any in this game, I'd love to see them for those times that I do since it always seems to be with people of the opposite faction.
And to the OP, Even as someone that has a really hard time finding RP in this game, I don't see any lack of RP areas. The game has planets to explore, and cities, even personal ships to invite people onto. It's like saying I need more places in my town to hang out with people at. I can do it anywhere.
