The scoring system doesn't factor in drone bails since there wasn't a player in those planes.
When you bail from one, don't you jump to the next. Then you have to bail again, and then a third time to get to the tower? Basically hitting enter nine times in a row...sounds like three bails and should be scored as such. Personally, I don't see why so many are so wrapped up about score that they'd do that, or care that others do it.
Now, I can see the frustration of climbing up there, getting close and then having your fun stolen by the dweeb who bails out at 6k so you can't get a kill. Wouldn't it be nice to have an incentive to stay and try to protect yourself - say bailing out of an undamaged plane anywhere near an enemy would be scored as a death instead of just a bail? Three bombers, three deaths. I'd think people would rather stay and try to protect themselves than to roll over quietly and give someone kills for doing no work. This is a combat game, isn't it?
