The relic weapon quest goes on for a long while, I've only just got my Animus weapon.
It's worth saving up myth tomes to get higher level armour from Rowena's store by the entrance to Revenant's Toll, its the stone stall in this pic
The main story improves after the ending of the 2.0 main scenario too, though "A Realm Awoken" (2.1) isn't as good as "Through the Maelstrom" (2.2) and "Defenders of Eorzea" (2.3). 2.1's main story makes you do some old content, where as the others don't lol.
