Yeaaaah, I get that people were getting gear faster then they expected, but I don't think they handled it correctly. Granted, I don't think people would have cared as much if the grind in there was more varied, but little variety plus a slower payoff isn't a good recipe for success.
Different ways to spawns S ranks would be nice, as well as a wider range of S's.
Edit: And yes, the lack of test servers is probably what is hurting this game the most right now. This is somewhat compounded by the fact that they're often slow to fix content that the community is unhappy with. I get that they want to avoid spoilers, but still I really wish they'd get over it and get at least SOME of this content tested before sending it out live.
This is especially true for new types of content.
If it's spoiling they're worried about, the MSQ post 3.0 has been paltry and I don't think anyone cares about Alexander's Goblin infestation.
