Lol. I still to this day wish that was a part of the live game. It’d fix so many problems pertaining to indirect fire and countering it as brits.
It would indeed be an improvement. I always liked the idea and thought it had merit enough to deserve being tested in an official capacity.
Another method could build on the whole point that British emplacements are also garrisons.
Reduce the cost of emplacements by about 210-280mp. Disable all weapon functionality until garrisoned. Remove all popcap from emplacements. The extra abilities from being garrisoned could be handled by: adding another garrison slot and require a second squad, or incorporate them into vet bonuses for the emplacement.
Know how vehicle crew vet imparts vet onto the vehicle they're crewing? Same deal for emplacements.
Maybe they could have magic passwords, or maybe they could be stolen.
That's how I always thought British emplacements should work in this damned universe where they absolutely for some unknown reason HAVE to have emplacements.
