I've been getting pathetic quality on synthesis ever since. I can barely hit 200 making items 15 ranks below me and on iron ingots hitting 500 has been impossible. Even with abilities like Sublimination and ephiany etc I get less than 70 quality and I've yet to HQ anything.
They appear to have increased the success rate and balanced it by nerfing quality gains. I'm not sure the nerf to quality was appropriate as far as they took it, but from a playability standpoint it makes sense that quality should be the challenge and not just basic success.
