What little time I play MA...
I find a field being vulched, usually hop in my favorite plane (P-40B), and see if I can get off the ground and fight. If I die everytime without even getting to fire back, I may switch to an A6M5, a Spitfire MkIX, or a P-38. If I still keep dying, I may switch to another field and take off in a P-38 to come back to the vulched field.
If I can't find a field being vulched... I look for the biggest red bar that is reasonably close to one of my fields.
Obviously, I don't score well by playing this way, nor am I much of a team player... I just come in to get some quick adrenaline hits by flying solo against really bad odds.
Sometimes, I at best delay a field capture. On a good day, the vulchers run out of fuel and ammo (after killing me a million times on the runway), so I finally get off the ground, chase them home, and the base survives intact.
My absolute favorite is going into a mess of Spits and N1Ks all alone with a P-40B and getting a kill or two before finally succumbing to superior aircraft and pilots

Score? What's that? I pay to have fun, so that's what I do.
