I have no issue with pilot rescue being implemented, I just strongly object to it being incentivized. Have it there for people do it if they want, just don't make it feel obligatory to those who don't want to do it.
As for spawn camping, that doesn't have an explicit incentive going for it. Bombing town centers falls into the same category.
TO the point about resupplying the strats and HQ, those being down affects the game in a global way and thus those players are affecting the game. In addition the rewards are not outlandish like those that are suggested for pilot rescues. They were outlandish, but they got culled back.
Think of it this way, if you lose two of your three B-29s do you get a 50% refund on the two you lost when you land your remaining bomber? No, you lose the full price of the B-29s you failed to bring home. Why should a Me262 pilot get a refund for a chunk of his perks that he lost when he lost his Me262? Certainly the pilot isn't it as the vast majority of aircraft have no perk price and they all have aircrew it can be safely determined that aircrew have no perk cost.
