Make it easier on people trying to buy

Let's say I want to buy some lighting crystals but I don't have any? Guess what, my job just got harder. I can't WTB them in my personal bazaar or my retainer because I have to have one first. If I only have three, then guess what? I can only by three because the limit on buying is linked to however many I have.

This is a basic functionality (wanting to buy something I don't have) that the game is missing out on. My only options now are either:

1. Hope someone on a LS is on who has one or can make one.
2. Hope it's in the market wards for a reasonable price.
3. Spam WTB in town and hope there's someone on who isn't afk, has one, and is willing to sell for a reasonable price.
