There is no one right way to play a Rogue. The Rogue is a versatile character that can be a scout, thief, adventurer, or assassin. Sounds like you're wanting the assassin route. The assassin is a master of burst damage, that one attack made from stealth. Combine that with various poisons or add-on rubs to the weapon and that first attack can be ugly. The issue is that is the only time he is truly devistating. So unless you can arrange sneak attacks over and over again the Rogue is not, nor never has been the parties primary damage dealer.
