All very good points, Miko2d, but maybe you're misreading the tone of my post. As of right now this is not a complaint, because even though the perk system is in place now, it is not counting for anything. I'm not currently being penalized for flying for fun. Now, that is.
But the perk system WILL be here soon enough (v1.06?) and just like anybody else, I'm going to want to try out the "hot" planes. Sure, I'll still prefer my old favorites, but to fly a D-9 or LA-7... mmmmmm

. That is, if I start playing for score. Don't get me wrong, I like the perk system... I think it will be very necessary to balance the arena. But base the perks on a more realistic scoring system.
I guess I do care a little about scores then. Hmm.
As for realism... let's say a Typhoon squad is tasked with an anti-armor mission, 1944. They go out and find two panzers and kill them. On the way home they run into four enemy planes and shoot them down. Are you saying that they will NOT get the kill credits for the planes because it was tasked as an anti-armor mission? Of course not, they will get credit for all kills.
It shouldn't be too hard for a computer to figure out that attack points should go into the attack category. It just seems pretty BASIC (pun intended).
But I don't care about points, really I don't! Really! Okay, maybe just a little. Don't we all?
