Titans are the weakest class and therefore the class that requires the most skill. They are good for close combat but don't have extra armor. Fists of Havoc usually kills only 1-2 because enemies don't group up together. If you are good you can wreck with shoulder charge but it's pretty easy to see it coming. If you want easy mode play a Voidwalker with Voidfang vestments. Throw a grenade in (axion bolt) before you enter a room and watch your kills go up.
