I think all the classes have amazing perks. Hunter, Invisibility and throwing knife are both really fun. Titan, With Helm of Inmost Light, FoH is very enjoyable. Also all the grenades for titans are really good. The Titans jump is by far my favorite. Warlock. Nothing is more fun than Bad Juju and Obsidian mind combo on a voidwalker. Also can generate a ton of orbs as a sunsinger.
