With triple exper on an HQ Leve it's not about leveling Weaver. You could level the class with cotton if you wanted to force it.

It's the Guild quests. They want HQ everything for those quests. I got my Wedge cap, my pants and got 96% of the Jacket for the 50 quest. They decided 96% wasn't enough and handed me junk. So I bought the HQ Jacket on the market and got my needle anyway. There is no way I will complete the 3000 achievement with fleece the way it is right now and I will need to settle with non-HQ green gear for the immediate future.

I should also point out, all green gear and a blue needle and I don't anywhere near enough Craftsmanship to make Vanya anyway so until they fix fleece, do it for Careful Synthesis II and no other reason.
