Striker with max Intellect and Discipline. Crest of Alpha Lupi to give teammates Orbs of Light since every other Titan Exotic is obsolete in the Crucible, except for Armamentarium. Lightning grenades, of course - Flashbangs blind people for a pathetic two seconds, don't even bother with them or Pulse grenades. Shockwave is the only good modifier for Fist of Havoc - Death From Above is stupidly situational and Aftermath is easily avoidable. Headstrong, as underwhelming as it is, is the only perk I use since Aftershocks only adds [i]one[/i] extra burst to Lightning grenades and Aftermath, and Transfusion is only useful with Shoulder Charge since Storm Fist is terrible. Don't use Shoulder Charge or Juggernaut unless you want to get put down by a shotgun long before you're ready to strike. Unstoppable is the only way to go. Max Armor to survive those pesky Tripmine grenades. Lastly, [i]don't[/i] use Defender, if you do, don't be surprised when every member of the enemy team activates their Super just to wipe you off the map when you summon your Ward of Dawn. Good luck, make Kabr proud.
