If its convinient I'll RTB, or sometimes if its a challenge (when Im all shot to hell).
But generally, the reward for RTB is far FAR *F*A*R* too meager to bother with in many cases. I think a succesfull RTB should double or tripple perkies for fighters, and bombers should get an even heaftier bonus! I cant recall the last time I saw a Buff make it back to base....why, cause it takes 30 minutes, and its B-O-R-I-N-G
