As I fly about looking for lotus I am noticing that there are way too many herb gathering nodes, especially tea leaves, and I am going to predict that herbs will have very little value in a few weeks outside of golden lotus. Everything else seems to grow in specific terrain but within those terrain there are way too many of them in a small area.
They should be more spread out, and I really liked cata in that certain herbs could only be found in certain zones. I maxed out herb gathering in the jade forest which actually surprised my guild mates. Tea Leaves -> rain poppy -> sha touched herbs.
There won't be much of a market for most herbs after a few weeks of blasting the market full with all the nodes. I'm suggesting that half the nodes be removed to add some value to the herbs, some competition among players.
I've also heard that mining nodes are way too numerous.
