Seriously, I have searched all over Ix, Alakol and Groddle Forest and haven't seen even a stump. I'm not at the house-buying stage yet so planting one is out of the question right now. I'm trying to finish the 'One, Two, Tree, Four, Six, Eight' quest. But I'm frustrated by the scarcity of the Wood Tree (this was a problem during Beta; but it seems worse now).
