Time is what the bomber pilot expended to get to altitude. He understood that high altitude is the best refuge. He's using good tactical judgment. His bombers are vulnerable at lower altitudes. He's not gaming the game or abusing the flight model.
Hmmm.
Regularly on this board we have derogatory references to "alt monkeys" in fighters, pilots climbing so high as to practically guarantee they will be able to enter the fight with an energy advantage. Especially common is people speaking of some P-51s/P-47s/P-38s/F4Us flying at "realistic" altitudes as being "crazy high" and "timid". (One wonders exactly what is illogical about airplanes which have the advantage in high-alt performance choosing a high cruising altitude...but I digress).
But when a buff pilot takes advantage of excessive free time, lack of a boredom gene, and laser-accurate bombing to shut down fights through toolshedding (Lets face it folks, that is the *ENTIRE* purpose of buffing in the MA. You don't do it for the thrill or because 20 minutes of climbing and setting up a bomb run is fun.) at realistic altitudes where they are almost certain to not be intercepted, this is just using good tactics?
For the record, I don't want to take away anybody's ability to climb as high as they wish. However, I might want to take away unrealistically accurate bombing, linked defensive gunfire, and quite possibly, the ability for one player to take 2 spare planes along with him on a sortie without paying anything for it.
