Stealth, however, has Light Armour, Sneak, Lockpicking, Pickpocket, Speech and Alchemy. All perfectly good skills when supplemented with a way to actually kill your foe. The closest it comes to an offensive power is Alchemy's ability to craft poisons, but even then you've no way to deliver them without dipping into the Warrior skillset. What else will you do when confronted with a dragon, talk him to death?
Are Stealth characters crippling themselves by levelling non-combat skills faster than skills than can put a foe down? Going purely off the Guardian Stones, you'd have to put extra effort into actually killing foes to be at the same offensive power as a Warrior or Mage, or have to make constant trips back to the stones to swap to another skillset when you're preparing for a ruck, needless micromanagement to make a Rogue as potent as the other two classes.
Hopefully I'm worrying about nothing.
