What to do while waiting for 2.1?

If you havent done fishing, give it a try. Just pull up youtube or any movie at the side, & wait for your rod to move.

Join an FC and make some friends. There are funny conversations to be had, and you can help out people in doing dungeons.

Get your Luminary weapon for your crafting/gathering class. Then stand around town showing it off.

Craft things to sell. Economy is slowing down, especially on my server, but some things are still selling well. Like Deviled eggs for example.

Train your Chocobo. Get a Lv 50 Whm, get a party of 4 friends with 4 chocos, Holy them to death. I saw a party East of Quarrymill doing that.

Hope these kill time for you.
Cant wait for Crystal Tower!
