They are... ... In 4e! (jk)
One of my earliest fan-press efforts was a Doctor Strange fanzine I published in Georgia, complete with official Marvel blessings (though they forbade me from including any part of the Doctor Strange logo in the masthead for fear of the public mistaking it for an official, rather than authorized, publication, something I still riff on from time to time ...)
Dr. Strange is a SORCERER, not a wizard. Get it right, noob!; )
Dak: I was referring more to Strange's sweet mustache, sartorial splendor and smoothness with the ladies, not his ability to cast magic missile as an at-will ability.
