Really now? I take 17's to 30K+ every other day or so but the rest of the time I'm flying light fighters looking for a tangle. Any bomber knows that you fly over the fight rather than through it, and pick off anyone who would follow you. Any fighter know knows you've got to jump into the fray eventually.
I think somebody's just posting while they're a little mad. 
bold statement is completely false.
People run from me, on a sortie basis and avoid the fight to come back later and kill me with some friends. I'm not complaining, just stating the obvious.
People will run from you for
1) no reason at all
2) to protect their score
3) to come kill you with their buds
4) protect their killstreak
5) avoid loosing perks (understandable)
6) because they plain and simply can't kill you 1v1
All of these reasons is why someone would run from
1 person. Imaging a group of them, or by gawd, an even furball. The only time these tards won't run is when they are the at gang pick fest over a base, or they are vultching the living hell out of imaginary planes.
To be honest, there is no reason for someone to "jump into the fight" other than the reason they enjoy the fight, in my opinion many people don't, they just want to rack up the kill, get perks, and protect their precious score.
B29 is practicly the same thing, people will ignore B29s while they toolshed to get their friends kills up by BnZing and vultching Il2s off the runway, or they will go ,as stated in this thread, to 40k and lazer bomb anything they can get their plane over to rack up their own score. As I can't reverse the decision that HTC has made by putting the B29 in the game, I think that it could be a contibuting factor to player avoiding each other at all costs, and scorewhoring it up.
The old saying of "be careful of what you wish for" come to mind.
