How about making some weapons that can only be used if the torso is the same type ?
That is Physical weapons that c an only be used with Physical Torso
and heat for heat
and Energy for energy torso ?
dont get me wrong , I am not saying All the system . no
I am saying keep it as is for the older weapons and make new weapons that cant be mixed with different type of Torso ?
This will add some varity for the game for people who want to try the new set of weapons. and will force people to try all kind of build types .
