Using salvage to build weapons or armor.

Using a modular system so you get more varieties of armor so you get unique pieces.

So wardens helmet for example; changing the helmet and faceplate.

Kensei, face mask (tash or no tash), helmet material and design.

Raiders axe: the shaft, change the shaft wrap, pattern

Colour can be changed etc, But there design prints would be found on the Battle field, rep exclusive. So every 10reps you get a rep set to make. The designs and colour can be bought with steel.

ATM salvage isn't really used apart for XP or a piece of gear you use and it's so easy to stack up getting 8-10k In a day maybe more
