I've noticed a dramatic step between the stuff my L6 fighter has done so far and the last few remaining level 4 quests and level 5s. I was pretty well breezing thru the level 4 quests, but hit a couple bastards at the end (Proof is in the Poison, in particular). I've started working on some level 5s for the various houses and it's been a rough ride. Not sure what the deal is.

Also, either the Rest for the Restless (Phiaran from Lady Napethe) quest is bugged or you've got to have some real search/spot skills. I've gone into the dungeon 3 times now, and simply can't get past a gate. I've tried every combination of valves and nothing works. Crud.
