I know I've often seen guys leave a fight in the middle of it, race home, land, and get their wtg, often leaving other guys hanging in that same fight as the desire to land the kill is more important to them.
I'f I'm getting critically low on fuel, am out of ammo, have serious damage, or a gaggle of red cons at high alt appears trying to pick me, I'm off. If and how many kills I do have is completely irrelevant. I try to land every sortie, even with 0 kills. Name in lights is not what is driving me, (unless it's like 5 kills in a ENY 40 plane - I'm not above trying to showoff

)
I will always try to help someone in trouble, but if I clear someone's 6, but if he just flies back into that horde of 12 red cons he better not complain openly about me not "helping him" again
