The selling point for Tactician in D:OS1 one, was not only to be harder but also fights to be different. If the difficulty is mainly achieved through bloated chance, that can be hardly said.

In D:OS1 there often were more and more special enemies in fights like the lightning zombies in the fight outside of the doors, making a fighter fresh and harder. There were also often speciel 'enemie' that just supported with an aura.

But in D:OS2 there seems to be heardly anything new to fight, only some skill and perhaps one or another aura?
