With the drop in price of Air Runes would it still be a good idea to Craft Air runes for a profit at x6? Or would the profit be so samll i could just aswell do Earth Runes at x3?

It depends if you are wanting profit or Experience. Personally, I would go for Earth's, as they will give more Experience, but you might want to do Air's.

As ouchy said in the previous reply, it all depends on whether it is experience or profit that you are after. If it is experience you want the logical rune to craft is earth and if it is contrary to that and you want profit/money airs would be the way to go.

If the profit margin is gonna be so small between earths and airs, ill just go with eartdh because of the speed
