I've not ever had an issue with "finding fights". Maybe it is because I'm not of the "feed me" crowd, I'm not sure. I don't expect to be spoon fed.
With that said, I don't think a set of bombers has ever had a free ride from beginning to end for the strats, HQ, etc, at above NOE settings. Again, it is random and those planes NOT making the dar bar are unaware they are doing it. No way to exploit it. Plus, out of 100 solo flights just how often does a plane not make a dar bar signature? Same goes for a horde, just how often?
Very few, I bet.
