The 104th use to have stats back in FC2 and it didn't affect game play then, I don't see why that would change now. It all depends on the person flying. I would rather have a higher k/d ratio then have a lot of kills. Some people don't care about the risk of being shot down, they just try to get the kill....eve if they are running into a SAM or outnumbered. I have seen things like that happen many times before a guy still chasing me when our SAM's have fired at him. It comes down to some people play it just as a game and they don't care if they live or die. Other people want to actually be good and fly according to that.
When we would fly as a squad, it didn't matter who got the kill, just as long as the guy was blasted out of the sky. Other squads are the same way, at least that's how it should be. Teamwork is always a big part in this game, although there are some very good lone wolves out there. There have been times that I flew hours with my squad and only got 1 maybe 2 kills, but I was ok with that.
