Your spawn secures the location pretty much, if it takes about 30 seconds for a non pro to crack through that door, the chances are for certain that an MTF's nlr ends and comes in kills all the ci cracking armory. This change would make that armory pointless. The armory in lcz is not an issue as gensec either go straight for d block or are much easier to deal with than MTF.
CI also have an armory that MTF can easily access once they enter too, we both have to fight our way to it how ever, balancing things out a bit.
