I'm definitely in favour of a "Way of the Rogue" - I think there's a case to be made for a melee character focused on Stealth/Evasion instead of tanking.
I've thought up potential bonuses for five levels of that skill. I wouldn't mind a "Way of the Wizard" either, although I haven't many ideas about what might go into it. There's some pretty big changes coming in the next patch though.
