Having recently collected all 12 Atma (only 96 hrs X.x), I am faced with an odd problem.

Which class gets the upgrade?

I generally switch classes based on what I feel like doing for the day, (pld/war/brd/whm/sch/smn ilvl86), not really preferring any one class over another. The time investment is to high to simply grind out atma and animus for all of them.
