I don't want to nag, but if I don't ask it I don't think I ever dare to enter the nameless dungeon again.
So here I go.

Today Taislin Woolhands organized an expedition in the nameless dungeon near Haven. Our first venture with relative lowlevels went very well, untill some people had to leave after which we couldn't continue and had to go back.
While the others went back my PC, Daeron stayed to explore the deeper levels of the dungeon to see what there was to find. When he returned he foudn the rest of the party still struggling to leave the upper level and he encountered creatures that hadn't been spawned before and much more than first.
This was the first point where I thought we got a little bit of good old DM attention.
A bit later we returned with a much larger and slightly higher leveled party.
Before I continue I must state that I think I don't die often, Daeron still having zero DT's.
But anyway, at the second venture, I couldn't help but notice the effectiveness of the creatures. My question is whether this was due to bad party tactics or a little bit of DM-guided carnage. At one point we were hit by a Xorn earthquake while as far as I know, nobody ever saw the Xorn. Apparently he did see us.
Really, I never died so often (3 time within 10 minutes, ouch, 32000 xp), the dungeoninhabiting Xorns being an important factor to that development.
So, I was still having a good time, but I just want to know if we as a party were fighting worse, or if a DM was helping the creatures a bit?
PS: I hope I'm not sounding to paranoid in this post
