But this is essentially identical to how vehicles work.
The problem with emplacements for me personally is that they are simply too cost effective (the amount of resources needed to counter it is about 3x worth the cost of the emplacement). Which is fine in a 1v1 where the emplacement has to compensate for the fact that it's static, but they become borderline OP (especially with cancer emplacements regiment) in team games where they can lock down key sectors with ease.
Vehicles are different though. The ones that are even remotely in the price range are threatened by small arms fire, even the lowley mortar put unbraced can tank a sturmtiger rocket which if my memory serves is the highest damage per shot vehicle in game no?
If brace is a necessary evil, which I think it is, it needs to play into the very important variables already in game, on of which is bleed. Brace should be a last resort to save the unit and its vet, not a pop at every inconvenience and buy time to hurt the enemy.
I agree that in 1s it's not an issue because map control is effected and critical mass of emplacement means little reactionary units, but in team games it can be so frustrating, both having a team mate that commits to the cancer and playing against it.
I reay think that being able to inflict attrition to emplacements would help. It would really effect good emplacement play much, but would add some sort of yeuld to forcing the enemy to brace but not being able to secure the kill
