I did satasha the other day and was about 40 min. It's long. I push one button in fates..2 if you count tab. It's pretty mindless. So far I have enjoyed everything about this game but FATES. Grinding fates misses so much of the game too. I tried it out from 20-30... Fast paced spammed ice...done. Tried on arc spammed fast knook 15-20. I would totally ditch Xp from fates and make it a seal grind. I understand there will be hard ways to level later on...so grab a full party and chain mobs 10 levels higher than you!? I bet it would work.
