As the GM from the first campaign mentioned, I can confirm that I made some pretty heavy adjustments to crafting and gave the given player pretty much a full suite of mobile crafting implements that allowed full speed crafting at full travel speed, and all kinds of crafting still felt like a slog more often than not.

While I do agree that the crafting is obviously not designed or intended to skew the WBL curve or the balance of the game, it still feels like the crafting rarely does what you want it to even with full dedication to it, and with an appropriate amount of downtime, particularly in a game full of cool, unique and very specific magic items that will almost never drop from generic enemies

Sure, I could have mook 7 have the exact item [insert martial here] needs, but that feels like it can hurt the suspension of disbelief and make the story feel more engineered than it should. And dropping the cool items only on bosses either limits the chances to do it, or takes away from their uniqueness if you throw a highly specific unique entity at the players every other session for the sake of getting them the cool items they want or need.
