Well, guys, I'll let you know how my attempt at the 'top 15 goes'.
Right now I'm ranked (well, I dunno, cause I havent checked)...
I was ranked 10 in GVs, 14 in fighter, and 30 something in attack last time. I had 1 good vulch in fighters that got me like 10 kills, but I got stupid and got killed instead of going to land them. Thats the only vulch I've had this tour so far. Haven't run a bomber sortie yet, but I'm not going to do the 'drop 1 4k bomb and go RTB, rearm, come back and drop another 4k bomb' thing.
Am I going to milkrun? Yea, most likely. I'll up a bomber box of B-17s and go hit some factory somewhere, but rest assured I'll drop every single damned bomb trying to kill the whole thing.
I'll let you know if it is possible to crack the top 15 without being to 'gamey'. I've never done dumb stuff like strafed my own hangars in attack mode, but I still usually end up with a pretty good attack ranking. Fighter ranking, thats pretty much a given for me that I'll have a good rank.
Only things that are left are the GV (which 2 sorties in a Flakpansie took care of for now) and bomber (which I dread because I find em so booorrrriiiinnnngggg).
