Having chase items is nice, to be honest. Keeps me wanting to run it here and there for the opportunity at something to sell, and the vast majority of MMO games tend to have some chase items in loot tables.

If you can't live without it, just do maps/gather/craft and make the gil. Or run content and dump the prior tomes on some of the hot materials to sell for some more gil. But I feel like having low-chance drop cosmetics in content, that are valuable to sell, is overall a good thing in a MMO. Keeps a reward present within content to make re-running it more exciting.

But if they can't use hairstyles/cosmetics as sought-after or difficult to obtain rewards, idk what they could really. Except for things no one wants.
