Poetics

[Rongway]

But it's absolutely not worth skipping the game just to avoid wasting them.

This, though. Poetics fall off trees. You will have so many poetics throughout your adventuring career that you won't know what to do with. If you really care to, you can spend them on crafting materials and then sell those on the board, but unless you're quite diligent about doing it (and I personally don't think it's worth worrying about), you'll find yourself capping often with nothing worthwhile to spend them on.

If you have inventory space, you might pre-gear your next job to hit the available poetics gear levels. But otherwise don't worry too much if you find yourself sitting on 2,000 often.
