RPG combat: Tanks, threat and aggro, oh my

Joystiq - On the surface, the last 10 years of role-playing games have not been momentous. Skyrim looks much more like Morrowind than Morrowind did Arena; Diablo 3 fits comfortably in the mold established by Diablo 2; there's a direct line from Knights Of The Old Republic to Dragon Age; and massively multiplayer role-playing games are still judged by how much they deviate from Everquest and World Of Warcraft. This is not to say that there haven't been changes. Certain narrative techniques, like moral choices for example, have been well-documented.
