True but none of these units are found in the same commander; JLIs also have a sniping role, while Panzerfusiliers have flares, G43s and AT rifle grenade (and better than Riflemens' too, ironically).
I just thought of anther way Fallschirmjaegars can be deployed differently:
Have them deploy in a 250 halftrack. Sure it's pretty much clown car strat, but they come rather late, it adds costs fuel to cost, but you gain a powerful infantry squad that has mobility, which also removes the whole spawning issue. For a doctrine that doesn't feature vehicles a 40fuel transport carrying FG42 troops would seem more reasonable than paradropping or nerfing their weapons.
This would give them a more unique fire-brigade sort of role that doesn't really overstep stock units. It might replace the Luchs if you're focusing on infantry, but it does shift the resource burden and, if used soon after unlocking, might mean setting back your tech/ vehicle strat, which of course might not be a good idea since it comes at a time where light vehicles/ AT guns are coming out.
So rather than being that behind-enemy-lines unit it becomes a sort of spearhead infantry.
The AT rifle snare of Pfuss is the worst snare in the game; it only does 40 damage and it disappears after 1 second which means it's impossible to snare a moving tank. It also only fires like half the time.
