WAI.
This is not a bug, and should not have been posted here. This is a whine. Could a mod please move this discussion to the general or crafter forums?
That said, non-crafters need the items too. They need them for getting gil. Restricting loot to just crafters is silly.
THAT said, it would be nice if the crafting mats were removed from the dungeons' boss chests. Either they should be given in addition to actual gear, or they should be available in the side chests with the potions. Getting crafter materials should not be in place of actual gear. That's just lame and makes getting the 2.3 "Divine" glamour sets nearly impossible. A new 50 will also have a ton of trouble getting Myth gear because of this change, making ST the only real way for new 50s to gear up when the 2.4 dungeons should have been a legitimate option.
