Regrettably, I am still unable to comment as frequently as I used to on these boards due to my job change, therefore I will not be able to keep up with this conversation as much as I would like. That said there is an arguement in Courageous Conviction that I think needs its own thread (in fact, I think my first thread on these boards dealt with this subject, I think I called it "I'm opposed to DM Empowerment"). In fact the thread can be found here http://community.wizards.com/content/forum-topic/3325196.
I enjoy playing D&D with people. Right now, my favorite DM is probably Plaguescarred. I've participated in many games he has run and I have almost always enjoyed them. Except once. He pulled a classic bait and switch and DM fiated away the party's NPC client. I hated that game. He actually had to ask me to stop commenting on it because he felt I was getting to negative which was not my intent.
I bring this up to show how not negotiating with your players can cause problems. I had no fun that series of sessions and my attitude negatively detracted from others experience because communication in this one instance wasn't clear.
I was reminded of this by iserith's conversation with kadim and Ramzour. I think its obvious that I side with iserith.
