Fate, fate, fate. Some people hate it, some love it. I'm in the latter group. It's fun meeting a new group to fate with it every hour or two. Alternatively, you can do dungeons, but it's not going to be as fast as fates. Also, if you have any guildhests you havent first time completed they're a good bet. Lastly, I'd suggest using leve allowances for DoL/H unless you dont intend to ever use them. They don't have fates or dungeons to help them out XD
