Welcome to the club.
If you wait long enough to pad your score or spawn camp, then one of the people you zapped took offence and came back and expressed thier displeasure in a personal and terminal way and you made the error of waiting around too long and paid the price.
Get in, get a healthy number of kills and beat feet back to a hangar, because you just became a target to either the gv's or an upset gv'er and he will roll a fighter/medium bomber to end your streak or someone will roll in based on someones call for help and do thier best to send you to the tower.
Should you be awarded the full perk count of your kills for making a tactical error? No, you made a mistake and hung around too long and unlike real life where you would be dead, here you just lose the perk points and wind up in the tower.
Fight smart and don't hang around to long in a perked ride, because someone likes the potential points just as much as you do.
Speaking as someone who would roll a fighter/medium bomber in on gv's as needed, I learned when in gv's not too hang around for very long, because landing your kills got harder and harder the longer you wait.
Note: I was not one of the dive bombing lanc pilots, preferred the B26 as it semi geared towards ground attack or the IL2 and one or two others.....
