Just fully unlocking the wheel would be a big help. It doesn't make sense to have a couple options locked but not all (especially since you can't even equip offensive items in the bottom track). Since we can still change it out in our inventory, all that does is make us spend needless extra time in the menu.
If you want to lock the items, maybe introduce locked loadouts as an option or in a survival mode, where you can only change inventory items and gear at the bivo. Though if you do that, you definitely need to unlock all six slots so we can put anything in, or at the very least so that we can put offensive tools and gadgets in the top three, and health/boosters/consumables in the bottom.
