You'd be surprised what two individuals can do.
Two friends of mine once gathered for a whole week, and spend the following week crafting. Flooded the market with low price pots. They didn't want the Gil. They did it because 'we had nothing better to do'.
Needless to say, they got a bunch of tells from solo crafters that were not happy :rolleyes:
Crafters bought their low price pots and sold them again for a higher price.
