In regards to the continuing 'weapon collection achievements'.
To craft new Azure and Crimson, it's 5 Prismantium Ingots (50 Prismaticite Crystals, 250 Mithril Ingots (500 Ore)3.5g, 250 Orichalcum Ingots (500 Ore) about 11g, 50 Ectos 2.4g), and 10 either Destroyer 6.5g, or Corrupted Lodestones 5.6g, plus the weapon parts; about 17g material costs each, or about 544g for 32 weapons. You get 8-9 Prismaticite ore by doing the daily drm's, so seems you'll be able to craft maybe 1 weapon a week, and find a way to farm or buy Lodestones, Ori, and Ectos (for those that don't have that stockpiled). I can't imagine any newer players who would be able to participate in these 'achievements', but who knows.
Though I'll probably do it over time, since I'm an achievement hunter (sigh), it looks to be a pretty long-term goal, and an expensive one. I'm feeling like those who do achievements are basically punished for wanting to complete stuff like this. That being said, achievements are obviously a personal choice. These are weapons that I'll simply craft and salvage. Maybe for some, it gives a feeling of accomplishment.
For my part, all these recent 'weapon crafting achievements' have been a real deterrent in participating in an aspect of the game that has previously given me many hours of enjoyment, and frustration, but ultimately gave me something to do and strive for! Now, I've actually been playing less, trying to reconcile myself into not being a completionist.
