The only time i craft now is when airship needs new components. I spent most of yesterday (about 12 hours, most of time AFKing) building 5 components (Odyssey) in a batch.

That 12 hours would be the same amount of time i needed to gather favors and craft i170 gears, but i rather spent it doing airship. Why? Because of the reward/return and the satisfaction of a TRUE progression.
