The moment you hit 50, get access to Foundation through msq. That’s the main city in Heavensward where you’d unlock DRK. First, buy all the 120 ironworks gear you can in Mor Dhona using poetics. Then go to Jeweled Crozier in Foundation and use gil to buy the rest of your gear at 115.

The only way your gear should ever be below healers and dps is if it’s broken, then you need to repair.
