Or, maybe you should just accept responsibility for your own actions and maybe take notice of what you're putting money/tomes/seals down on is what you truly want instead. You can hover the cursor over the item's name to view it's stats to make sure it's useful for your current class/Job anyway, so it's not like you're in the dark about what each piece of gear is (and even if it didn't have that, the tome gear names are pretty easy to determine for what class they used for).
