Weaver's use lightning shards as well, just as armorers use wind. No one gathering class can get all the materials needed for a particular craft, and I rather like it that way. It forces players to either buy from gatherers or level one themselves. It's a great supply and demand chain, and one of the backbone's a good game economy is built upon. The market is made in such a way that you can choose who you buy from, so you should never need to overpay for items either.

Right now it's a fine balancing act. Too much heavy-handedness could ruin the whole thing, and I'd rather them make minor adjustments here and there than radical ones.
