Obviously I have not had a chance to try it out, but on the face of it, they replaced what was in some ways the only ranged castable skill Primalist had with yet another melee skill, of which there were already several. Having an elemental melee skill added when there is still Tempest Strike seems especially redundant.
You can change GS to be a ranged cast, but you have to go with a staff and pay a mana cost. Maybe the vision is to have Primalists be only able to cast totems and tornados and stuff at range so there is almost no overlap with Mage roles.
