For future reference, I would advise you to adjust the balance. I think this expansion demonstrates how much the Nihon and, to a lesser extent, the Imperial factions outperform all the others. The "super soldiers" from Dreyeria don't surpass ordinary adventurers as much as the characters from these two factions do. A group of "normal" adventurers (let's say, a southern party) would have been wiped out much earlier. Instead, they were able to defeat bosses in just two rounds, just like they defeated the mobs. In general, as I already wrote to you on Skype, you need to either significantly reduce the power of the Rhemians and Nihon, or bring the others up to their level. Well, except for the Araidians. They are supposed to be that way by design.
