The job you're thinking of is Geomancer. There was a strong thought among the forums it would be in EW because they traditionally use hammers and people thought Gaia using one was setting up for it. Alas was not the case. It's not to say it will never happen but as it stands right now with EW we have 5 melee DPS, 3 ranged physical dps and 3 ranged magical dps. Who knows what they will do in the future.
