Well.. For a Titan, such as yourself, you get a quest for a Shotgun at rank 2, and an Auto Rifle at rank 3. Depends on what class you are. Titan: Shotgun, Auto Rifle Hunter: Sniper Rifle, Hand Cannon Warlock: Fusion Rifle, Scout Rifle Rank 2 is Legendary, Rank 3 is Exotic. (All those weapons are CLASS EXCLUSIVE. Meaning they can ONLY be equipped and used on the classes that get them via the Quests.) My Warlock has both the Rank 2 and Rank 3 weapons equipped if you'd like to take a gander. 3:
