There's way too many people over-reacting here.

1) We don't know at all yet how much character time you need to get up a tier.
2) The hats ALL have the bonus slots in them.
3) The only difference is cosmetic and a slight bonus to doubloons gain. (Which from what I've seen in the preview, is NOT the limiting resource for crafting)
4) If you really want a different hat, you can buy it from the barter system.
