Thing is, the newer generation of gamer see this as "content", when it's more 'passive' content than anything. For example in a lot of shooters there's a '250 headshot' achievement, you don't specifically go for it since logically headshots are best way to kill things which means you get awarded for doing 250 headshots..doing your normal activity.

The crafting achievements are done in such a way that you'll end up near or at your goal after you level normally, because you will no doubt do most of the requirement by time you hit 47. Gathering..what do DoL do? They gather. They can't have it at just 4k in 1 spot, most people who played since 2010-2012 will most likely have their tool if they gathered for their synthesis rather than buy or they were already near it given how spread out and varied resources used to be.

As said, they're passive, designed to be done in your everyday activities, if you purely focus on it, especially as a level 50 when it was already introduced it will seem like 'content to do', but that's not what achivement systems were designed for, but knowing how developers just don't care anymore, other MMOs tend to have achivements that are in place of content, i.e "Slaughter 80 (monster you'll never, ever encounter in your playtime) then visit (NPC you'll never, ever encounter in your playtime or care for and get a title with +30 STR.)"
