Windowed fullscreen
Native: yes - this is an option under Display -> Display Mode -> Windowed (Fullscreen).
On a multi-mintor display, depending on which monitor the window is initially launched in before setting Windowed (Fullscreen) mode, it is possible to run two or more windowed fullscreen instances of World of Warcraft (or other compatible games, like Starcraft II) on the other monitor(s).
