I dunno, weren't the majority of attachments made through Goldsmithing, with Alchemist being the second?
Either way those attachments were pretty cheap and nobody cared for lolPUP so I doubt there was a big market request granting noticeable profit for professions.
I thought alchemy during the leve75 era was profitable early on for some cursed gear and mostly for the Hakutaku pop item?
I remember some of my LS mates making some gil (alas not huge amounts) thanks to those.
I'm sorry for the (very few) ethically correct crafters around who worked their ass to level professions, who suddenly felt all their efforts go to waste when the meta-game changed to R/E centric, but I still liked that type of game so much more.And I'd posit that's why the game went so R/Ex-centric from Abyssea and onward.
Fuck crafting, fuck greedy assholes.
