Look at my problem! First off, I use Gambit Prime Armor only, that means I need 4 sets of Armor to start with. I also have to have all 4 sets with all 3 affinities! Now if I want to masterwork all of it, it costs 750 enhancement cores per set! 750 cores x all 4 sets x 3 affinities = thats 9000 enhancement cores! See any problems? I had 400 enhancement cores before Shadowkeep. Now I have nothing but 2 master-worked pieces of armor.
