Overlap? Since when did obers have camo and ambush bonus?
They took away Faust but made the unit field earlier, so you could argue they diversified it more. Obers don't come that early so you can fit a couple of squads in your build quite easily.
Also AT capability just doesn't fit the role of falls, they were notorious historically for being caught unprepared when something as simple as a Bren carrier turned up in Crete for example. Suffering heavy losses.
That's because in Crete, Fallschirmjäger dropped without guns, most of which were never recovered. Your Bren story is at best anecdotal and at worst completely fabricated.
You should avoid comparing this game to history, especially since you are clearly not well versed in real-life history, you seem to prefer nonobjective and politicised versions of events.
As for the service record of fallschirmjäger units, they performed with distinction outside of the role of paratroopers, throughout the whole war. I would refer you to the service records of the following:-
-Fallschirm-Panzer-Division 1. Hermann Göring
-1st Parachute Division
-2nd Parachute Division
-3rd Parachute Division
-4th Parachute Division – included volunteers from the Italian 184th and 185th parachute divisions
-5th Parachute Division
-500th SS Parachute Battalion
-600th SS Parachute Battalion
-Brandenburger Regiment
All were or became Fallschirmjäger divisions that served with distinction, outside of their intended paratroop role. Particularly the Brandenburger Regiments and the 500th SS parachute battalion see [Operation Rösselsprung (1944)].
The problem with their inclusion, is that they are disproportionately involved in massacres of the civilian population, with two divisions accounting for approximately one third of all civilians killed in war crimes in Italy.
Lets let this game be a game and leave historical accuracy to games like steel division. Otherwise we'll have incredibly outnumbered axis armour and soviet tanks that can't hit anything and fail catastrophically when fire is returned upon them.
