First off, the scale of game you described is way beyond Wargame's regimental combat team level.
Second of Fallscheimjager'44 would be shit-tier because they are basically light infantry with odd support weapons and shit tier support tab since all their units would come from Lufuwaffe feldivisions also Germans stopped mass dropping paratroopers after Crete so your troops would move at the same speed as Heer or Waffen SS if not less due to SS usually had the priority of roads in late war Bulge is a very good example of how FJ interacted with SS Oh also in case you are wondering most of the shit during WW2 are transported by rail Germans already realized in 39 that their shitty Autobahn wont be able to handle actual military formations moving over them Americans tore up the western sections of Autobahns badly during Ruhr campaign of 45 so yeah shitpost is shit
