A nice adjustment to the cargo disks as they go up in lvl would be if the radius at which u can use it at when its set down. Not only will this be nice in a general sence, but also as you are crafting in more dangerous areas, if a monster walks by your disk, you dont have to get AS close to attach it and make your getaway.
Im not suggesting any HUGE bonuses here, just a slight increase throguh the tiers.
