how about just limiting the amount of perms a cc can have, forcing people to buy more cc's. and how about certain items going with certain items ex. if you first choose a lockpick for your cc you can only equip raid items such as breaching chargers and what not, but not allowing them to equip a medkit or a healing grenade, you can easily find a partner to do a raid with you that has these healing equipment.
In my eyes this makes sense you don't see normal class items crossing over with other normal class items. cc's should be the same.
