Holy s**t did your whole guild farm elements
Fire 1, 2, 3 i doubt someone will buy.
Fire 4, yesterday a guy gave me same amount of gold as the number of my elements, so in your case that would be some nice 10m
Fire 5, 6, 7 no idea.
Earth 2 > 5 not sure if anyone needs it. But i think people need Earth 6 so you could sell that one for a nice amount.
Water 8 is needed the most i think (from all water lvls), so don't know if anyone will buy those other lvls.
Wind 2 and 4 are the best. 3 is a little too common i think, but 6 is also not the runner, just put ~4m for water 6 and you should sell them.
