So I craft a lot and I have not had an issue with crafting with old stuff you had a chance to fail with the rotation you used in crafting. But with the new SB content my 3 main crafting classes have not had an issue crafting anything in fact its so easy I have someone I know who made it into a 2 part macro. But in an interview recently Yoshi P was asked about fixing the crafting classes because it was harder to craft in SB than in HW. I know that if you try crafting something that isn't one of the 3 main crafts you chose it can be hard to but isn't that the point? I say for those who have a hard time maybe you should look another way to do the rotation or get melds and gear on that can help you. A site that helped me and my best friend craft through HW and SB
