I originally agreed with the OP as I am always shot down instantly by buffs and when I see others attack them they tend to fail as well. One poster said the LW had a 3:1 kill ratio against US buffs so I checked AH scores. Here's some representative ratios of kills vs killed when going against B17Gs: FW190A8 = 3.0, Me109G-14 = 2.2, P51D = 1.9, Spit IX = 1.6, P38J = 4.0, F4U1C = 3.9, Me262 = 8.4 (as you might expect). So, doesn't seem too far from reality. I don't like that answer, but that's the data.
I do think, however, that bombing is way, way too easy. I never fly buffs.. i.e. absolutely never. But I took up some Lancs once, read the online directions for the first time while in the air, and proceeded to destroy all my targets perfectly. That's just too accurate and too easy.
