Ok, to be slightly less sarcastic.
I don't think the HE111 would bring anything to the game, at all. We already have one 1940 German bomber, we really don't need another one. We can run a BoB scenario just fine with the Ju-88 and Ju-87. We don't need the He111 or Do17, which offer similar performance with a slightly different shape.
What the game could use, in my opinion, is a lot more Japanese planes. We've got no Ki-43, no Ki-44, no Ki-45 (which as far as I know were the 3 major IJAAF fighters from 1941-1944) and no Ki-84 (which would be the IJAAF's major 1944-1945 fighter). We've got no early-war USSR planes, only 1944-1945 stuff. Sure, the La-7 sees massive use in the MA, but good luck running a scenario. We've got no Russian bomber, I think one of those should be put in before we get another hangar queen. Now granted, most of the planes we don't have will be hangar queens in the MA, but they fill holes in the scenario planeset.
