Relic is useless since ilevel 120/130 weapon is easy to get and after that you will be using expansion weapons. Altrought, you might wan't to grab ilevel 90 relic because that is so fast to get and then work for your way to i130 weapon(which is fast to get too). You should do every dungeon atleast once because that unlocks dungeon roulettes for you and they will be useful later. Then just do all the level 50 main quest to get into HW content. Those quests should give you gear now to get pass the ilevel reqs. If not, use poetics you accummulate from dungeon runs to buy few pieces of i120 gear.
