the positives out way the downsides and bots can already do it, the armor core system is are way to customise are undersuits
more body types would be great to we all come is different shapes and sizes and it would help spice combat up instead of always having the same target over and over again
armor attachments, we should have the option to equip a max of 3 helmet, 3 chest plate, 2 shoulder attachments on each these attachments being knifes ammo and other stuff with most of not all attachments being universal
back packs, belt attachments and arm n leg equipment that effects both limbs like if i have pistol ammo on my left leg id have a pistol holster on the right
more customisation on prosthetic limbs would be nice too like swapping versions and changing colors
