I built my gear for Critical Hit Damage &amp; Critical Hit Chance in all my pieces (Predator) I could do it to (Weapon damage is 24,300, Critical Hit Chance is 59.50%, and Critical Hit Damage is 120%) and my House (SMG Damage Bonus = 28%, also Vicious &amp; Deadly as talents) &amp; Lightweight M4 to a the most critical hit damage &amp; chance, and still I can NOT put a rogue down. I barely take down his health. Even when I do take his health down, he'll just stand there and hit his heal and he's as fresh as when I first encounter him. He doesn't even have to waste one single clip to take ME down. And what's the deal with the Ninja Bike- what does it do that's so special?
