Rapid synthesis fails have received quite a boost to durability hit, as obnoxious as it is. D:
Oddly, I was just doing a rank 1 weaving leve at rank 11 Weaver, and I actually succeeded every single synthesis for the two items for the leve - including several bold synthesis once I'd passed 85% progress. I finish both items with 80+ quality and ~60 durability, easily.
However, once I'd finished the two items, and went to synth the spare remaining materials from the leve for skillups, I started failing horribly and never made it past 60% progress on either, despite it being the items I'd just synthesized with ease. I'm going to assume this is just terribly bad luck on my part, though I'd like to know if someone else had anything like this happen.
