Since day one of D2, I've felt like there is something f*cked up about the RNG system. In everything...or at least everything that seems to matter. Milestone powerful engrams, braytech schematics, vendor rank up rewards, etc. It's like the game gets latched onto whatever it gives you first. I've turned in five braytech schematics on my hunter alone. I've gotten four winter wolves and one frigid jackal. Regarding powerful engrams from milestones...I can't turn in the first four of them (crucible, clan xp, flashpoint, heroic strikes), get all helmets, and think that nothing is wrong.
