Not to mention the little things they do to make it worse.
There's no reason hat mk3 holos disappear from guild shop at lvl 60. There's no reason that the tier 5/6 rancor drops full stun guns but heroic cannot.
But worst is that the highest tier of all challenges only drop an item that need another 50 salvage to compete. At least carbantis and syringes are commonly used on their own. Biotechs and binoculars are worthless without the other half. Plus the Tac challenge......
