Reaching Level 30 on Impossible?

[Helios]

Lex,you won't reach level 31 on Impossible regardless of your EXP boosting. I've only played one game all the way through since this topic, and have been using a +30% EXP boost throughout it. I'll definitely hit 30 before Murock.

As for levelups, I did 42 different iterations across 14 games testing when would be the best time to start taking leadership every level, and it always has come at level 8, regardless of class. If I take leadership earlier or later than that, I always wind up with the same or 80% of the time, worse Atk and Int if I deviate from that plan. Perhaps there are exceptions to this, but I figured I had enough data points to be contextually certain and not experiment further. Note that in my experience at taking leadership at level 8 that Mana or Rage will be lower by a level or two than if one waited to take leadership later.
