Its pretty fair to say that the Enhancement trees are an overall success, with a few minor gripes here and there. One complaint I have from a class fantasy perspective is the lack of earth abilities in our tree. In the enhancement spec tree, we currently have one earth ability: sundering. I think the longevity of the spec tree can be preserved better by incorporating earthen abilities in the bottom left of the tree. PW is already pretty controversial, so replacing it with something like unleash doom/earthen rage can allow for not only better fantasy, but open up more nodes for the tree for more potential abilities (maybe earthquake/covenant/entirely new ability). A smaller change would be to replace elemental blast with earthen spike as a MW spender. Elemental is getting Ele blast as a spender, but already have tons of earth with earthshock and earthquake, so it makes sense to give enhance an earth spender.
These things are really minute, but I feel like earth is an integral part of shaman and I don’t want to lose that. (especially since Evoker has some really cool earth abilities)
