Karnors Castle = Slowest XP in game?

[Ashimar]

except solo-wise, but group wise it sure feels like it. Thats why you always see shamans and whatnot soloing in there instead of grouping. Even with good groups who chain pull via a monk the xp seems slow. One time i was in a group with a full group who had a ranger + paladin. i had to leave because the XP penalty was kicking my ass. People used to joke i was at lvl 56 for like 5 or 6 months. Well it was due in part to Karnors. If we could get all the folks
at KC to start hanging out at much better zones like Charasis, Sebilis , or the Hole that would be awesome. I don't say Chardok because every single time i've gone there the group ive been with wipes.

Maybe because KC is closest to Port rings?
What you think about KC?
I' don't hate it completely. i would love a Runed blade, Ringed Mace, or Oggok Cleaver but have yet to see one drop.
