Dead: How do we keep a Support from dying?

If supports would stick with their team mates, they would live longer. I ran around with a turret for my kills, while I healed a few guys. I juiced, killed a few more guys, then retreated. My team won 2 out of 3 games like this. I just constantly used the heal gun, only switching to shotgun for combat. Throwing random airstrikes into enemy territory is also good. ;-)
