Just wondered for what you wanna add this aircraft? Model D is predecessor to famous E (emil), then if it will be added in game it would be higher in stack and earlier to research than E-1. Therefore it’s worse it in specifications. But if you’re wanna see this in game how low it’ll be by battle rating? I don’t expect players paid interest of low BR vehicles just because we have even F-1 on 2.7 (ARB) which players abusers would research very fast and they’ll never think of predecessors again. Therefore it could only expand the row and no more.
As i see we could expect pretty heavy weapons which is unusual to Germany on BR lower than 2.0. First German aircraft with guns is He 112 B-0. As I know that gaijin’s thinks of balance and keeps in mind of weapon balance in game. Looks like it won’t be lower than 2.3. And even if add a version with only machine guns It’s just the same as E-1. It makes sense only for arcade battles if you wanna use more 2.3 planes per battle.
The D-2 and D-3 would never enter production because introduction of the Established Emil. I even asked TEC, and he would live to see it in game, and it would complete the production BF 109’s. It was THE BF 109 that got thing going in the right direction
