Does anyone else find it really annoying to have to redo their defenses whenever they unlock a higher mark forcefield? I usually build the needler/laser/etc turrets just in front of the forcefield and the sniper turrets just behind. When I try to place a higher mark of forcefield, the higher mark covers a larger area and so all the turrets are now covered and do -75% damage, so I have to move them. That's expensive in terms of metal if I have a pile of Core Turrets, and takes a lot of time if you place them carefully to maximize density (like if you're trying to pack them under a mod fort's shield modules).
I know it would be a big change, but I'd rather standardize the force field size, at least for the force fields available to humans.
