So, if I legitimately transfer a character to another world such as to play with some friends/access housing, I would be stuck with everything in my inventory and would not be able sell anything I had prior to the transfer? What about people who travel to another world to buy an item that they need but only find a stack of items while they only need one?
I have no issues selling on the market board though I avoid items such as classical armor as it is too much trouble to craft and the market too competitive (and when you look the the price of mats, many crafters seem to have a “math” problem). There are many other things that are far simpler and cheaper to craft and sell for more. When it comes to stacks of items, I sell in smaller stacks and can thus price higher than the bots and people selling stacks of 99. There are many items that sell pretty well and pretty fast.
As for undercutting, unless it is an item popular with bots, I sometimes undercut or sometimes price higher based on history. If I had the lowest price and someone undercuts me, again I use the history to help me make a decision: maintain my price and wait, undercut or buy the discounted item and resell it.
If I see items priced abnormally low, I won’t hesitate to buy them all and resell them at a mark up or even to an npc as people can sell things well below what npcs will give you. The person got the price they were asking and there is no reason for them to complain.
The opposite is also true: simple vendor items can sell for many times their cost (bought some stuff for 400 gil, resold 25k). Playing with the MB can be fun and the short lived crowd effect can be amazing to watch.
If the upcoming data center travel includes the ability to use the MB we can expect wild fluctuations at first and then it should more or less equalize after a while. I am more worried about the added congestion at aetherytes it may bring during hunts.
In the meantime, SE should take action against the RMT buyers, not just sellers. Sellers don’t care if they get banned. They’ll just keep making accounts and use bots to make gil if they can turn a RL money profit.
