I've had this for a couple of days now. Is nobody else playing this? If so, that's a shame. I'm having the most fun I've had in an rpg in a long, long time.
Apparently the augments (but not skills) you have purchased from each vocation can be transferred when you switch vocations. It's going to be a long grind trying to collect the best augments from each of the nine vocations to make a character strong enough to travel solo or with just one pawn.

From what I've read, people are saying it has taken them anywhere from 15-25 hours to reach level 9 in a single vocation.
Anyway, I'm about ten hours in now and it keeps getting better and better. The combat is still amazing as well.
