All the World's a Stage, and all the orcs and humans merely players. They have their stories and their characters; and one player in his time plays many roles.
Playing Warhammer recently has made me think of more features that WoW could add in order to create a better roleplaying experience. Far and away the most important one, to my mind, was the Tome of Knowledge. WoW players really need an in-game resource they can refer to as a standard for information about the Warcraft universe, and having this at hand, roleplayers could do a lot better than they can today.
Knowledge is the most important thing, of course, but there are other features Blizzard could add to the game that would help roleplayers too. I'd like to address a few of these things, and see how much they could really do for us. Player housing is a possible feature that gets talked about a lot, but I have my doubts as to whether or not it would really help roleplayers all that much. Another issue is one that is more important to me personally, and is another feature inspired by my trial with Warhammer Online: looking at interactivity between characters.
