One of the travesties in AH is the ability for Lancasters to up at a field and dive bomb gv's, however shallow that dive bomb may be. None of the heavy bombers in AH, save for the Ju88, were designed for pinpoint precision in a dive bomb. There is a reason the Ju88's have dive brakes.
zippo was spot on, and I believe karnak has it backwards: The fact that Lancs have over %40 of their kills be gv's is not at all in line with what they did in the real deal. It is a blatant abuse of a game piece, and it is a travesty. If the heavy bombers are at 10,000 ft and they carpet bomb an entire area around the tip of the arrow (spawn point) in multiple passes and they get a few gv's, then fine. THAT is how they killed gv's in WWII. They did it completely and totally indirect, they dropped their ordnance for "area effect" on an enemy strong point.
bmwgs said it perfectly: anyone can take any stat and bend it to their need and you've done exactly that, karnak.
