The only good thing on the test server is the way recalibration works now. You get 100 allocation points/range whatever and that determines your stat caps and they are way higher. For example, I had a 2 stat chest with 858 SP. I moved it onto a 3 stat chest that had 260 SP. Not only did it not hit the cap, I had room left over so it can still go higher. I'm really glad I saved a ton of 450 gear with high rolls on my mule alt.
It still would be nice if they let you switch colors. They could put in a 75% cap on recalibrated colors stats, so it could be sort of a hold over til you found a better piece. I also think color requirements either need to go away completely or be lessened a ton. And only low minimums like 3-5, and no "no more than" bs. The number of a color you have should just give you a small percentage boosts of that stat type. 5 reds? 1.5% weapon damage per. Armor for blue, SP for yellow, etc.
Brand sets could use some looking into as well. I never get to actually use a full 3 set with the way color reqs work. And on the rare occasion it's happened, the 3 set effect is something that has zero effect on my build, so I have to replace it. Accuracy? Ok. Headshot dmg? Ok. MMR dmg? Uh, I use a scoped rifle, asshole. Also the random %specific skill SP. I don't use drones, fuckhead, but I like the first and third set bonuses!
