No, I really don't need or want GM to be 'open and honest' about their reasoning for how the things run behind the curtains. I don't want the GM to strop the game and ask "It seems this fight is not going well for you, would you mind if I had some allies to come to your aid?" or "This session is starting to get a tad boring, would you mind if I sprung some bandits or a goblin ambush on you?" Seriously, just run the game the way you think is the best, I trust you, and I don't want you to ruin the game by explaining your decisions and asking permission.
