Titans aren't OP but you can do well if you play smart. For Striker Titans: Flashbang grenades work well in small rooms, setup kills, and over all hit n runs. Very fun to use. Pulse grenades are good for area denial and to control opponents movement. Lighting grenades are great for setup kills and direct kills. I primarily use lightning grenades. For Fist of Havoc, choose whatever your good with. I go with the wave since I can get more kills that way but I do use aftershock once in awhile, especially in control. Helm of Inmost Light with the wave perk on is an awesome combo and aftershock is also good since you can deny an area and sometimes opponents just stand on the aftershock trying to get a control point only to die. For melee aspect, it honestly doesn't matter for a striker titan but i use discharge since usually if I'm that close there are multiple opponents and I can at least get their health down for my teammates. When I don't have my super, I use shoulder charge. When I do have it, switch to unstoppable for the moment so you can finish your FoH. Also, spec for more regen than armor. In crucible, getting back your health lost is important especially if your in cover against multiple opponents. Strafe in and out of cover, kill an opponent, stay in cover, regen health, strafe in and out again, and kill the other guy. Also, go max intelligence and discipline. Strength is useless on Striker Titan in crucible since if you are trying to melee, shoulder charge is better. For the armor you want to go with Armamentarium, Helm of Inmost Light, or Peregrine Greaves (new exotic). Armamentarium will give a huge boost to your discipline and allow you to carry more heavy and special ammo however it's exotic perk allows you to carry an extra grenade (doesn't matter which kind). This is great since you can heave grenades at one choke point to stop an enemy so that you can take care of the one trying to flank you. Helm of Inmost Light allows you to superman into enemies but with an added bonus of Aftershock or Wave. Great for when enemies pile up on a control point since not only can you kill most of the enemies but the stragglers and the people who got away from the initial impact have a nice surprise waiting for them. Last is Peregrine Greaves. Now I don't have this exotic but a person that I was on a fireteam with had it setup and he was demolishing people. Shoulder charge is already good but with the greaves, as long as you connect, the opponent is dead. Warlock with radiance? Dead. Bladehunter? Dead. Titan in bubble? Dead. Doesn't matter these greaves are monsters. That said, you still have shoulder charges weakness and 9 times out of 10, if someone sees you coming and they have a shotgun, you will most likely be dead. I honestly don't know about ACD/0 Feedback Fence since I don't have that nor have I seen anybody with it so your guess is as good as mine. Hopefully this helps man. I was crap in crucible before and my K/D and K+A/D were abysmal. After watching others play who had good end scores during a match, I was finally able to get better scores myself. Just got to be patient and not be afraid to retreat if all else fails. Anything over 1.0 K/D is great since you were helping the team succeed. Getting 20 - 25 kills is cool but when you have 30 deaths, it's not all rainbows and butterflies EDIT: Finally at work, haha. Added armor stuff
