Is it something that I'm doing wrong, or the trading aspect of this game is dead? All I can see being listed on the market are black crystals and gems. There isn't a single posting for an outfit for any of the classes, there are 0 weapons, etc.

It is likely related to the daily register limit of 5 items which means that certain lower quality items and less popular classes may have no items being sold. If you look around various class weapons and higher grade armor the market is still there.

No ur correct the market is dead and it is intended like that. 

If u look up all black pearl items there are plenty of them because PA is earning money with it. 

When it comes to silver items the players cant get them in suffiencient count to list them on the market Glyphy etc. 

They ensure that u buy the stuff instead of playing to get them. Even if Glyoh are impossible to get on higher grade atm. 

Just very high price silver items are in the market here and there because u need to cash to get the silver amount to buy it 

The whole game is just full of mechnics to fk u up in oder to stimulate u to spend money so that the rng willl fk u up again.
