I feel the same, like only 3 enemies at a time in the Soul Cairn, although from all the lag I've got from the DLC recently I don't think the Xbox could handle more than 10 at a time.
Agreed! I want uber enemies that top-tier level 81 players struggle with. I don't care if it's inconsistent with the lore, just give me at least one challenge worth bragging about.
I was really expecting a seen right out of Dawn of the dead or Army of darkness where your just hacking and fighting wave after wave of undead. Throw in a couple uber boss enemies to lead the undead army and BAM instant panic, but instead I walk through the Soul carin like I owned the place.

But the Soul carin wasn't the only spot that gave me that empty feeling, there where several other places that could have used a couple more NPC's to face.
Another thing that's started to bug me is the vampire side, as you go through you face the DG but you also face groups of vampires

To me this is very silly, it would be like doing the DG side and having to fend off both vampires and other DG members, why is it then as a vampire you are not only facing the DG but also other vampires all dressed in the same vampire armor that your wearing and all the members of Horkon's court?
