BenchmarkReviews wrote a guide on how to easily defeat The Warrior end boss in Borderlands 2 and how to farm him for XP, you can read it over here.
Borderlands 2 is an exciting game that pulls you into a fantasy world that's been done a hundred times, but finds a way to give it to you like never before. While the game itself is a hybrid creation with familiar ingredients that taste of Eve Online, World of Warcraft, and Fallout, then seasoned with hints of Battlefield 3 and Call of Duty. Players assume the role of a "vault hunter" in one of four combat disciplines: Commando, Gunzerker, Assassin, and Siren. The character then fight bandits in first-person shooter format across a vast array of maps, but unlike most FPS-styled games, each level means better loot and tougher enemies. In this article Benchmark Reviews explains how to easily beat 'The Warrior' end boss within 'The Talon of God' final story mission, then we show you how to farm him for XP and legendary purple weapons over and over again.
