why not ?
Too busy with RL activities to have someone count on me in a game. I go afk a lot, can't respond, and can't stay fully focused when on. Not fun for me to disappoint someone over and over and have them ask why I didn't help or check six or do whatever. No interest in then being ejected from a squad or doing my own quick thing while squad is focused on something.
I have a lot of fun on my own, am learning and enjoying all my time flying and fighting when I do. Aces High is more of a time filler for me than a primary activity. That's why I'm on a lot, because a lot of the time I'm doing something else, and don't want to constantly log in and out.
