I know it sounds shallow, but I will admit that in IMOL's Warbirds, I looked forward to the medals awarded for points/kills, I would look at how many kills I had, and how many more to go for my next.
Kinda gave me sumthin' to shoot for.
'Course now we have perk points, but, sumhow it just doesn't fill the spot that the rank/medals did.
Although the "rank" thing to me was meaningless, I dug gettin' the medals, especially after a really good sortie.
I felt the system Hitech and crew at IMOL came up with was kinda like feedback as to how well a pilot was doing.
I've noticed that the stats can be interpeted many different ways, depending on what exactly you are looking for. I.E. overall ranking, fighter ranking, attack ranking, etc.
