The lights are on
I have to agree and for a long time I was also afraid of losing my points, but eventually found that as long as you waited until the next game started loading, your points were safely stored.
That's not even the main issue I have with it. I just wish that people could use the lobby as... well as a lobby. Give people time to quit in a civil manner so that I don't start a game that is 9v3 (that happened last night).
I also noticed that if you quit through the menu in-game, then it adds to your percentage in one of your stats. Mine is 9% right now. Roughly half of that is from wanting to stop playing, and the other half is when my squad didn't get into the game so I would quit to rejoin with them.
