So apparently the Special Site for 5.2 lists "Crafting/Gathering Overhaul" despite the fact they JUST did an Overhaul in 5.1.

This tells me that 5.1 is not final and that they have more adjustments to make, so it could be that a lot of the back-and-forth in this thread is irrelevant as maybe they already have plans to address the concerns with the lack of difficult crafting endgame.

Just as long as they keep the leveling process being relatively easy (like leveling DoM/DoW jobs is), I'm content with 3+ star crafting being hard.
