Heh. It wouldn't be a surprise to know that people at Wizards read OotS.
I like the article - I've passed it on to my Bard player and we'll have to see if he'll pick up on it.
This article really highlights how multi-classing can work brilliantly in 4e - offering all sorts of odd synergies and mixes that aren't immediately apparent. I'm sure the CharOp board on the Wizards forum is going crazy over this one.
