And several months later, my server's Water Cluster market has fallen back into its original pricing from when I started. The only time your item gets undercut severely to the point it will never sell is when the demand drops to "unneeded." The Grade 1 Glamour Prism Market has currently dropped as most people have already glamoured the items they wish to glamour and/or crafters have caught eye on a currently "active" market. Eventually, the market will bounce back up to its static pricing unless new crafters entering the market stay in the market or a demand increases.

There is nothing wrong with the marketboard currently. It's just people want unreasonable things at unreasonable times. You need to understand supply, demand and trends when you want to deal with market boards. This is why those ahead of the game in the crafting department yield more gil per patch day vs. those who start entering the market afterwards because the demand was fulfilled before late-comers
