Once the automatic side-balancing option was implemented, I activated it and have been enjoying it a lot. I'm happy to be part of the effort to equalize sides, and I get to fly with people who's handles I recognize but have more often flown against. Also its great to be occasionally on the same side as Silent's murderous guns!
If I could make a couple of suggestions: First, have a buffer of at least a 2-player deficit before being switched automatically to the low side after a sortie. I can be frustrating/confusing to be in the middle of working with a local group of players trying to take a base, when at the beginning of a new sortie you suddenly realize you're on a different team because the player balance changed by just 1 pilot. This would occur less often if the side deficit had to be 2+ players before the auto switch puts you on the new low-numbered side.
Second, an audible cue would be a helpful notification if you've been switched to a new side, i.e. Windows "Tada.wav" or something like that. In VR, my message text window isn't as prominently located as it was when using 2D full screen. Most times after I end a sortie and go to the hangar, I won't realize it if I've been side switched.
(Another idea - maybe the hangar interior could have the country's flag hanging on the back wall as a decoration, and an additional reminder of what team you're on...)
