wetrat - the reason I maintain that k/t is irrelevant (for ME) is that I prefer to try to fly "realistically", by which I mean with a purpose in mind - field capture, field defence etc. I have said once before that the P47 ace F. Gabreski got about 35 kills in two wars spanning about ten years - in AH k/t terms he was crap!
That is why the k/t is so gamey, and irrelevant - to me at least.
Just two days ago, I worked with two other guys to capture three enemy bases which could have been used against us and caused us to fight a two front war. With those bases captured, we had a war on one front only. During that session, the only kills I got were bombing GVs that had spawned to defend vehicle bases.
I think that the people who give credence to k/t (and there are many) are the same people who hate the pizza map (and there are many). I sort of like the pizza because you don't necessarily run into LA7 interceptors looking for quick kills. If you would stop and think about it for a moment, an aircraft carrying bombs is not going to be seeking a high k/t. Comprehensive though the AH stats may be, they do not show the contribution a pilot has made to field capture, or to field defence. And this is one reason I'm looking forward to seeing what the Mission Arena has to offer. The other thing that k/t does not take into account is side switching to whichever side is winning - not realistic, and not an option in the real war.
As for k/d, yes - much more relevant. I could show you score sheets in which I have a k/d better than 5/1. But that depended very much on what I was doing, and with whom. When I first started in AH, I struggled to exceed 3/2! -because I didn't know anyone, and was flying alone for much of the time. No voice comms back then, so fewer 6 calls etc.
But it seems some guys sacrifice k/d for k/t - would that be why we see so much suiciding in this game? Fly-till-U-die vulch crap because a new plane is only a mouse click away...

My advice to any score potatos is not to get to wound up about any particular stat if you're planning to fly the Mission Arena - and I can see why some won't want to - lol. My prediction is that the whole pattern of scoring will be completely different.
