| Well, I would definately go with dual wielding for a Warfare+rogue since you will be using swords for piercing damage and to synergize with blade honing. Using dual fast weapons will make critical strike worth it (and theres a lot of 'blue' item swords that give bonuses to rogue mastery. i.e. Dual wielding two Fell Blades is a whopping +4 to critical strike), but onslought might be good too, I dont know. Thats probably more a matter of taste. Throwing knife is a great skill, at least on normal difficulty, and flash powder is good for when you are getting mobbed.
I would most likely go 50/50 strength and dexterity stat wise, or maybe 70/30 str/dex to get better armor earlier on since theres no healing skills in warfare and rogue masteries. That means I would get the +res and +dodge passive skills from warfare too to minimize the incoming damage. |
