With the recent changes to Raiding Damage per Second (DPS) Warriors in the latest World of Warcraft patch, warriors should again be a viable component of an overall damage selection for both 10 and 25-man raiding. While the debate still rages over whether Arms or Fury specialization is more powerful, it's generally agreed by high-end raiders that fury provides more damage, especially if a Combat Rogue isn't available to apply the 4% physical damage bonus from the Blood Frenzy talent deep in the Arms tree.
The generic, widely accepted talent selection for raiding Fury Warriors is an 18/53/0 build, with several Fury points left to personal preference.
Nothing should be taken in the Protection tree, as the returns aren't sufficient to justify the point allocation. In addition, with the advent of dual specializations, warriors can easily have a secondary tanking spec, so an "off-tank" spec is truly an outdated mode of thought.
In the Arms tree, players should select 2/2 Improved Heroic Strike, put in throwaway points until the third tier, the pick up 2/2 Impale, 3/3 Deep Wounds, and then 3/3 Two-Handed Weapon Specialization. Players may opt for 1/1 Anger Management, but it's not a truly maximum damage build.
In the Fury tree (and this is going to be a long list), players should select 3/3 Armored to the Teeth, 5/5 Cruelty, 5/5 Unbridled Wrath, 3/3 Improved Cleave, and 5/5 Dual-Wield Specialization. From there they should further branch into 3/3 Precision, Death Wish, and Flurry. From there, they can pretty much pick up all the remaining Fury talents, save perhaps Furious Attacks (unless you plan to go play battlegrounds, it's a dps loss) and Heroic Fury (situational at best, waste of a point at worst).
At this point you should be full specialized for a level 80 character, and ready to go crush monsters and get fantastic items of a purple variety. Best of luck.
