If I'm looking to do a character down the Completionist road, how exactly does that work? From what I understand, I need to level each class, with each life taking more exp, up to the third, which is then how much exp every life takes after that.

However, does this have to be 20 levels in the class for it qualify? What happens if you have a splash? Right now, I'm 17 Rog / 1 Fig / 1 Mnk, and about to hit 20. Would this count as my "Rogue" life if I were to go for Completionist?

Thank you for your time.
