Gunslinger
For all the prospective sharpshooters in Destiny, the gunslinger class is the one for you. This class imbues players with the ability to use a fiery hand cannon that can cause a high amount of single target damage per each target hit. Given that you can only fire three shots and can cause critical damage, having good accuracy is a must.
Along with this is a throwing knife that, if mastered, can instantly kill a Guardian in the Crucible or deal a high amount of damage to one enemy. While the Gunslinger can use trip grenades to catch foes off guard, the most important thing to master is landing your headshots. Plus, if you add the Celestial Nighthawk exotic helm, you can do an almost stupid amount of damage to targets with a single Golden Gun shot.
