You can Reverse Engineer all campaign gear or atleast belt, bracers, ear, implants etc.
Then you can sell them, all crystal, mats from chests come worthless. Also you can Re camp gear to get mats if you could do unlimited runs takes appr 3 hours to do denova hm and sm not talking about Voss world boss and Kp what are easy comms.
It's fine with 7 days limit, enuf content and to get best geared you need to raid alot each week 1-2x to get BEST possible gear:
Like: All best armorings/Mods to your full camp gear, implants, belts, bracers all augment slotted etc..
Point is to get best gear to yourself, after that start building off spec, and companions of course
