It is in my experience that people who enjoy playing the game play as what are referred to by my close friends as "LEC" or, Low Expectation Classes, such as bards.
That's what I play. Alot.
Thus, optimizers and folks who enjoy pwning for no reason would play a Time Mage.
People who want to take apart the game piece by piece for a really interesting character would play a Thief specked for combat.
See what I'm saying?
