Hey guys what. If you tag enemies first at any level, and have a friend outside the party kill it for you, you get full EXP and you can get chain bonuses! Takes bout 40-ish minutes to level blu from 50-60 in Azys Lla when getting huge chain bonuses. But clearly you're in the majority of people that don't realize there's other ways to power level outside of a class change exploit they used to have.
