If you care more about your k/h stat than having fun, that is probably what you'll get. The more i play, the worse my stats get because I don't care anymore.
I fly 2nd and 3rd tier planes and usually get less than 1 kill per sortie (mostly for lack of skills) but it's way less stressful than worrying about my stats.
I think it was tour 97 or 98; I played out the last two weeks all for score. I finished 19th overall (score is a JOKE) but I was miserable and worried that I wouldn't make top 20. Never again.
Loosen up and just fly what you feel like. Bail if there's no fight. Nobody cares. You'll spend more time fighting and less time setting yourself up for a fight. What do you want to remember after you log off - the good fights you had or how your stats aren't going so well?
