I think this quote from Michael is pretty relevant to the discussion of the Rogue. We don't necessarily need more classes, just the availability of the cards that those classes would posses. Classes that bring in different equipment and/or different combinations of slots for equipment are really all that need to be added. An inclusion of a Ranger character would also potentially be an inclusion of a Rogue character, all depending on how you equip your dude's deck. Granted, we already have a Priest, Warrior, and Wizard, so the idea of classes seem to be pretty important. If nothing else they're aesthetically pleasing, and give you an idea of what they'll be built around. Actually, now that I think about it, I'm pretty sure certain items can only be equipped by certain classes. Maybe we do need more classes. I think we do, although I still like the idea of making our own variations of the classes; how we'd customize our characters with theme and such.
