Honestly, i think the best solution right now would simply be the "brutal A.I" that they claim was too merciless. in addition, giving the player the option to tune the difficulty themselfs. This would prolly be something like a slider for Health, Armor, Experience, Gold and Action Points. Anything like this would make me 'content' enough regarding difficulty, without being unrealistic. However, in the future i do hope they'll consider tuning their hardest content a little more aggressive, or give us a way to do it ourselfs. either trough options in a menu or ingame by completing various challenges.
