EDH reminds me of a game like Munchkin. Everyone slowly advances their board and holds the good stuff back because the first person that does something actually threatening gets dog piled on. So you want to be like the 3rd person to make a big play, since people might be out of sweepers and other answers by then. But really that's true of any multiplayer game of Magic, not just the format specifically. I don't mind politics in games, I just don't think Magic is a particularly good game to have those dynamics play out.
