Hm...yeah, i know what you mean, i just came out of the castle of Ulm, and the encounters inthere were almost as frequent as in Sacred LOL. If you know where you're going, i don't have a problem with it, after all, it's all XP, but if you're running around not knowing exactly where to go, it kinda sucks to fight the respawning critters at the same spot again, and again, and again, and again, and again.....etc...
Also, the lord of that castle wasn't much of an housekeep, i've run into bats (that also can fly under water !!! ), scorpions, and even hunting wolves !!! What kind of lord let filth like that run around in his stronghold ?
