The issue with cost on Hyperion is 3 fold.

1) Good Crafted/Melded gear is difficult to make better then darklite which can be easily obtained in 4-5 days of spaming A.Keep or Castrum:mer. Which is gimp compared to af2 which you can get in 2 weeks.
2) You can see what people are selling. Because of 1 the low demand and high supply people are easily able to undercut each other. Which will result in things selling for near nothing.
3) It is stupid easy to do everything. 100% chance to hq still, crazy easy to level crafts (I went from cooking level 39-42 with leves in 35mins.... I bought food from the AH and turn it in for double the gil and 20-30k xp per turnin.. yea good design SE), Way to easy to gather. I can get a stack of hq and 3 stacks of nq in less then an hour... the demand will never be that high. So as the market gets more saturated the prices will keep droping.

SE made some of the best crafting and gathering in the mmo world... and combined it with the absolute worst economy model of any mmo ever developed.

People saying gear is no longer a money maker.... This should be a red flag something is seriously wrong.
