Camp fires. I'd like to see more of them. It's a pain to backtrack multiple levels of a dungeon just to rest up. I realize it's to discourage the Baldur's Gate method of fighting, resting, fighting, resting. There are some spots where a fire would make sense but there isn't one. For example, take the cave to the southwest of the Knight's tower. The thri-keen enclave would be a perfect place to rest. Instead, I'm forced to go up two levels and camp at the bear cave. Bit of a pain.
How about this: after a dungeon floor has been cleared or some other parameter is met the player may build a campsite. This way we can eliminate some of that backtracking. It interrupts the flow of adventure when you find yourself running back and forth.
I have somewhat mixed feelings about this, but after having played the Orc Stockade dungeon (which, to put things mildly, makes the cave you're talking about seem extremely generous when it comes to camp fire access), I'm beginning to strongly suspect (and please correct me if I'm wrong) that a certain colored reptile in charge here is vehemently opposed to making any concessions on that front whatsoever. You go in well-prepared and survive more or less all the way through, or you don't go in at all...
That being said, from the little I've seen so far of the game it seems that the general principle of "accomplish something first, then unlock a camp fire" is being applied in several instances, although perhaps not in the way you'd like (the bear cave you mentioned is one example, the locked house in Corinth is another).
