I thought the swap to poison on Staves/Wands was to give Geomancer's a weapon that scaled with their skill passive damage boost.
I agree with the suggestion. Earth seems underutilized, and Crush/Pierce makes more sense if those are the only sources using it. Not much reason to have an extra stat that is rarely/never used, and the fact that Earth damage isn't even boosted by any skills makes it even more likely to get forgotten.
