The point of Specializations was to fill the role of some of the now near mandatory lvl 50 Cross-Class abilities. They were meant to allow those who only wanted to level a few Crafts to be able to HQ their Endgame Crafts. Omni-crafting has always been available, and yes it can be a problem when everyone can Craft everything, but with HW they made it MUCH more difficult to reach omni-craft levels, while simultaneously easing the Endgame for non-omni-crafters. Those who were willing to put in the time and effort were rewarded with the ability to omni-craft, but with Specialist recipes no matter how much time or effort I'm willing to commit I will never be able to Craft every Specialist recipe at any time. Unlocking the Soul Crystal limit would have been a fair trade-off to this as I could have spent the next few weeks worth of Red Scrips unlocking Specializations for the rest of my classes, but as of right now that doesn't seem to be happening.
Specialist Recipes aren't the end of the world of course, but they're a thorn on the otherwise beautiful rose that is Crafting D:
