Should you give up on VOG? No. But is the above true? Yes. VoG isn't for the person who only has an hour to play. The emotional satisfaction of getting a team to work together for 2-3 hours to accomplish the challenge is a primary incentive to complete VoG. You should at least be up front with your teammates about your time limits. I've done the VoG with multiple teammates swapped before. It does become inconsiderate of other people's time investment if you are up front and plan for time management. If you truly have such an unruly life that you can't control your own schedule for 2-3 hours then you may need to consider 1. Not placing yourself in a team event that your going to surprise quit in; or 2. Use the forums and grab some friends that understand your limitations and will work with it. I've used the forums for group finding enough to know you can find someone that will work without temporarily detailing another group that didn't realize you only had 30 minutes to play.
