What would you do for them though? Like i think they should've never had a snare, so that should stay gone imo. Their ambush bonus is really solid. They also have strong grenades that can be combined with that stealth to powerful effect
I'm of the mind they were mostly fine before the change. The ambush bonus is a nice addition and I think any unit attacking from stealth should get it. Previously the snare wasn't an issue due to their squishiness and cost, I don't think it would be one if their dps is returned to the old high but not attack across no cover and still manage to win somehow high.
Ambitiously
Perhaps (and hear me out here) changing their vet 1 to reinforce on field (by plane, that Flys over the map) when not in combat. That would let them remain in enemy territory BUT let the enemy know they are still there... Somewhere....
But conservatively,
I'd take a closer look at the doctrine and return falls to their former power level. A single apsectof a commander being the only selling point is never a good idea
Mash the ostwind into the flak emplacement slot and combo them as "air defenses " or something and see how that looks. Then there are 2 units that share the weight of the commander instead of making falls OP to make it attractive
