To complete this quest you need to kill a lot of orc. So you can say that the exp points from killing those orcs is part of the quest. <img src="/ubbthreads/images/graemlins/think.gif" alt="" />
Not if you're a Survivor. You take the underground tunnel (minimal enemies), jump out, bomb, return. I agree that experience should be awarded for the quests more than the killing. Killing is a method of doing the quest. So is sneeking, talking, or any other bizare means. I still like
Deus Ex. Zero XP for killing. You only get XP for completing tasks or making it to "checkpoints". The danger in making you way via combat, stealth or street-smarts is about equal. It just depends what you've trained in.
