Usually want a fight, but in addition to situations outlined I gotta say I've loved some LR escort. Doing historical style high cover, swooping in to scare off the fighter lining up on my buff -- and not taking the bait to drop down low if the bogie dives out. Love those times all my buffs get home -- and especially like when they OK release so can tangle with the interceptors for a bit.
And, being a journeyman (between newbie and vet), I'll take any landing I can get -- like 'em better with kills, but like landing better than a chute or ball of flame.
