FIFO mode for at least some marketboard items?

[sharknado]

This would just cause people to list 99 of an item for an insane amount of gil.

And nobody would buy it while others still could start their listing at a different price. This could lead to some price fixing if sellers on a niche item agree to some fixed price and quantity per person over time... but if they undercut by 1 gil on a 100k+ item then it's not really driving the price down. It would be just good if there was less of 1gil undercut automation.

Current WoW system that was mentioned is FIFO and you can list as you see fit - and most people follow the lowest price bracket (if it's realistic) instead of undercutting as that 1 extra gold is PROFIT :P
