they said because they balanced empys and relics before the new jobs they would not be added. (this is why blu and on arent on relics) although i dont see how a excalibur in the hands of a blu or a mandau in the hands of a dnc would be at all overpowered or need much balancing at all. BUT they did say that these jobs could get mythics as they would be balanced for the only job that can equip them.

I believe they said they would have artifact relic and empy armor too, but i bet if anything at launch we might have artifact in game (maybe even statless as i think happened for some jobs after blu was added until they know what kind of things to add due to player style with said job.) and after they see how we use them add the higher level gears.
