ALMOST IMPOSSIBLE TO SELL ANYTHING!

[Asiaine]

What are returning players and new players suppose to do to sell their stuff now and make some gil?

You can try selling it through other market wards. It does not have to be sold in Ul'Dah only.

If I knew there was a cap of how many retainers can be in a single market ward or if I knew all current Uldah market wards were capped with no space for any new ones, I'd of started in Limsa or something.

You do not have to start in Limsa Lominsa to have a retainer there. I started in Limsa Lominsa and have a retainer in Ul'Dah, so you can do it the opposite way. You can also commute between the two cities by teleport and airship.

But also, what are the chances that Limsa or even Grid's market wards are not 100% full as well? What are we suppose to do now?

I would say there is a 95% chance that the other markets are not 100% full. Won't be tooo hard to look, surely?
