I always ask if help is needed when i happened upon two guys in a fite. otherwise I'll stay up watching, 80% will say to stay out, and I do. There has been several times when they will ask me to stay out and the friendly gets shot down, and I know the eny con is in pretty bad shape, I'll let him go. actually once, i got shot down by the guy , i buzzed him and shot bb's way over his head to say hi, well he followed me and shot me down. I flew straight and he was in a really bad shape, i wasn't gonna take advantage of the situation, I figure he deserved an extra kill. I dont do that often but sometimes I do.
