Erm, how is the He219 less appropriate than the Ta152?
Not such a great example. I mean something that didn't make it out of prototype-ish stage (arguably the 152's proto stage is previous 190 models - something like 219 doesnt have such long direct precursor history) and/or saw negligible/no combat and/or was historically insignificant and/or adds nothing useful or novel to MA/historical arenas..
IMO Probably the main "pro" for adding the 152, before being a cheap dev addition, is that it's "the" 190. You come to this game to fly and fight these machines, and down the strand of permutation of design elements that is the Fw190 family, the 152 is IMO the optimal iteration (something between D-9 and H-1 like a 152B with short wings, low alt engine, 3x MK103 would be perfect).. The optimal iteration of one of the main "schools" - "BnZ". The He 219 just doesn't strike as many of the right cues for inclusion, even though it's not a good example.
I'm hosed from 12h workday. Can't articulate what I mean well enough, sorry.
In any case like you said, removing anything already in game is non sense. The 152's merit oughta be argued in a separate thread.
