Thread: What should i do now i've finished 2.0!

Ilv90 is required for some of the later main scenario quests. It's pretty easy to get so I wouldn't sweat it. One way to gear up is by working on unlocking your roulettes. http://ffxiv.consolegameswiki.com/wiki/Duty_Roulette A few of the roulette dungeons are attached to the main scenario, but most aren't.

EDIT:

Also someone brought up a good point. You could do the crystal tower quest chain. CT>ST>WoD. Labyrinth of the Ancients and Syrcus Tower only need ilv70. In order to do World of Darkness you'll have to get ilv90 though.

As others have said, work your way into unlocking & completing more of the story. You're going to need to do it to access 3.0 content anyway. While doing so, I'd recommend to as least doing the Main Scenario roulette for the soldiery tomes it offers. Buy soldiery gear with said tomes as these will be able to help you in dungeons that reward you poetics.

The FATEs needed to unlock Labyrinth of the Ancients are solo-able with yourself and a chocobo, so long as the chocobo is a healing chocobo.

If you don't mind grinding FATEs for Atma, the Atma relic should tide you over for a bit, but I would recommend just saving up tomes for a weapon you can use in its place (that way you can go back and advance your relic at your leisure).
