I could see a rogue Toranite excell in criminal investigations and espionage for the security of their faith or nation. When given a warrant or fulfilling the clauses of probable cause, their skills to get around locks and traps are vital. Perhaps street saavy bounty hunters that learn how to blend in, shadow suspects and gain information. As for the honorable fighting and sneak attack paradox, sneak attacks aren't necessarily low blows. They are hitting exposed areas of the distracted enemy for greater damage. Archers making use of the feat I envision as snipers and sharpshooters, firing from cover at just the right time as the enemy is unaware. SWAT teams and military men in the modern day do much the same thing lawfully. Walker Texas Ranger takes cheap shots and sneaks around all the time. It's not so much what you do or how you do it, but why you do it. As long as you aren't using your rogue skills to commit crimes and cruelty, you could play a rogue Toranite concept with ease.
hehehe makes me think of an gov assassin.. They do the dirty work that regular forces can't for the good of the nation.
