The MT defenses are unnecessary and often overkill, changing the layout of the facility which is weird and well unrealistic(why in the name of satan would the foundation fortify a cafeteria without knowing about an attack).
CI already has to go in without any knowledge of the current defenses or men present at MT, on top of that the grenades that CI has are easily countered, especially now cryo is gone or will be gone.
RDC is barely used and has existed for a while, personally i wouldnt mind a rule saying you cant use it without a proper reason but the current situation is acceptable and not problematic.
Point being: do something about the MT defenses which are unnecessary as well as it being easy enough to hold an MT raid on your own until back up arrives(without defenses), you can even retreat to the ez toilets hallway to funnel defenders even more.
