Q:
Misunderstood (ascended recipe)
You could try contacting support to see if they could help you out here.
Account Bound refers to the recipe consumable itself. Think of it like account bound food – you can move it around to any of your characters, and not sell it to other people (hence, account bound), but once you eat the food, it only gives the effect to the character that ate it.
But yes, some sort of warning about this has been requested several times already.
[Soulbind on Use] would be nice…
…Silly question, but you crafted all the way to 500 without noticing that unlocked recipes were character-specific?
10 laurels and 6g isn’t something to sneeze at, but I’m not sure I’d call it a small fortune, compared to the costs incurred crafting to 500 and building an ascended weapon. By that point, I think players should generally understand that crafting progress and unlocks are all character-specific.
Could more warnings be beneficial? Sure. But that’s the case with anything that doesn’t include explicit hand-holding, and crafting as a system seems to clearly establish its rules long before a player should be buying ascended recipes.
Sorry for your misfortune, though! Mistakes can happen to anyone.
