Hunter. I love the way they look (e.g. helmets and hoods) and I've always enjoyed a rouge and stealth types. I've also always been fascinated with old west gun fighter types. Hunters fit both of these themes well. And shadestep in PvP has helped me escape so many disadvantaged gun fights. It is definitely my favorite PvP class due to the evasiveness and speed. The thing I hate most about them is their gauntlets. I don't know why Bungie insists on styling their gear with one arm having something ridiculous protruding out from the shoulder or elbow and the other arm look more sleek. It's like they despise symmetry at Bungie. The Titan is a close second. I love that they are both tanks and with the Titan skate, the fastest class in the game (super hilarious). I also love the support that a Defender w/ Helm of Saint-14 brings to the table. My least favorite thing is that certain weapons don't fit well with the class or their lore. Like a Titan running around with TLW in the crucible or whatever... seems silly to me. I just feel that Titans or sort of meant to be auto rifle and Shotgun wielding characters. Warlocks are great too but definitely my least favorite of the three. Their melee range and grenade arsenal is amazing! Their jump is the worst though and drives me nuts. That is my least favorite thing about them.
