It would be neat if the player's ruck and chest rig configuration affected his item access times. So if the chest rig or harness placed the primary magazines across the front, primary reloads would be faster. Same for grenade and sidearm placement. Having a quick access pistol mount across the front of the chest would provide faster transition to secondary than a drop leg thigh holster, etc. This would help simulate the tradeoffs an operative faces when selecting his gear set because as of right now, it seems to be mostly a cosmetic difference that simply allows for greater weight/item capacities.
