Even if there was no gear from quests themselves, you can just use your levequests and pick the ones that reward an item. None of the story instances have any meaningful dependency on gear. Ironically, since Isgebind pretty much one shots anyone but the tank with his line AE, that makes gear less important as you quickly figured out you simply cannot get hit by the line AE, ever, and with that ability out of the picture gear becomes irrelevent.
