Two cents about the experience thingy.
I log in other people's games to give a hand and joke around, but I notice that people do the game in a sort of a linear fashion. They always seem to settle down in doing one and the same stuff and just want to crank numbers up to overcome the increasing values of armour. So, for instance, if you go to face the Lone Wolves leader at level 13, they go like, 'No, we need another level.' The thing about the two wolves having 100 magic armour each and being susceptible to charm goes ignored almost entirely across the board. I think the experience thingy is due to the exponential explosion of armour. Interestingly, thing are quite balanced until level 12.
