Enhancement has Windfury totem to help DPS with their damage to a degree. Restoration has mana tide totem to help with mana regen on particularly long fights but from what I can see elemental brings no utility to the table with their totems. And please correct me if I’m wrong here.
So I propose a change. Turn Skyfury Totem into an elemental totem they can set down and then replace the PvP talent with greater versions of their base counterparts (enhance gets greater windfury totem, resto gets greater mana tide, etc etc). Skyfury makes sense to give to Elemental as it benefits all casters and healers.
