Krusty,
If I saw a buff dot on dar just at it's own feild moving slowly outbound, I would say to myself easy pickins outbound. Then I would up a TA152, A9, or A8 with a big gun package and climb on wep to be waiting above the buffs.
It would be akin to all countires CV visible on dar to everyone. But I'm just pointing out allied bomber streams were expected and german fighters had ample warning to get in position. Since all planes show up as red or green dots, why not adjust the dot so we can tell if its a buff or a fighter.
At this point if said buff killing complainer cannot use fore thought to his ride selection and wep to his climb advantage before he engages...well...we can respond to his whine with a big round of "DBD"....Dumb Buff Doodler.....

Honestly if I could use dar to track buffs I would spend more time flying bomber interceptor missions. As it is I hate loitering around waiting for them over hot areas.
