Just read over what was discussed about crafting in the live letter. Sounds like when it comes to the rebalancing of skills, their aiming to adjust it so that if you have NOT taken the time and effort to gear optimally and prepare yourself that you will find hitting HQ on high end crafts harder. Which in my opinion is how it should be and something I've pointed out, for High end crafts you should prepared beyond what you would do for just leveling. For those who have decked themselves out in full HQ 430+melds/440 with food and pot, alongside a solid rotation HQ will be do able. If you have not gotten to the point or taken the effort then it will be far harder.
