Rage + Flesh Sacrifice + Scoundrel investment + Backstabber + Dual wielding + Vault + Guerilla = 3 AP, easy 600 damage, lined up for a backstab, and it has travel that does not cause surfaces to affect you or enemies to opera you. Grenades are icing on the cake, and since anyone could use them, I wouldn't think it fair to say they're strong on rogues. I'd just say they're strong in general.
Doesn't Rage only boost your critical chance to 100%? That does nothing for a Rogue, who should always have a 100% crit chance because of backstabbing.
Dual-Wielding + Vault + Sneak (for Guerrilla) is 4 AP, and Guerrilla is pretty useless because at only 50% extra damage, it doesn't increase your damage per AP over just simply using regular attacks.
