The Paragon (Warrior) is by far one of the best DPS class rift.
Either Orc or Troll Shamans seem to be the best for dps. They both have racial traits that can be activated to increase your DPS a little, temporarily. Other than that, there is not really a "best".

The current warrior tier, tier 11, is called Earthen Warplate (for DPS) or Earthen Battleplate (for Tanks). See the related link.
Depending on what the build is used for (raid trash, bosses, solo play), an Affliction build is probably the best all around. A Destruction build might be better for clearing trash in instances, but will use far more mana than Affliction. With Affliction, you also have the health returns from Soul Siphon and other talents.
I have a priest on spinebreaker, I've found my best talent tree build has been in discipline. Discipline allows you to be an effective healer and dps for leveling though some usually go for shadow priest. my priest is a level 65 and has a 6k crit.
Demo for raid utility during 25 man raids for the sp buff. Destro for large hits and PvP Aff is currently the highest dps build, and used for long boss fights and PvP as well.
It depends on what you want the Paladin to be...tank or dps. Tanking go protection and dps go retribution.
for dps, invest your talent points into feral, so that way you can do mass amounts of damage as a bear or get critical hits as a cat
There are a couple things that decide what the best dps class is.1. Do you want to be melee or ranged.1.A Do you want to be magical or physical ranged dps?Mages are excellent at putting out ranged dps if played right. they are excellent at AoE (Area of Effect) dps, damaging a large number of mobs at the same time.1.B Physical ranged dps is liimited to just hunters so they are the best dps for physical ranged classes2.A Melee classes get in up close, rogues are excellent at getting in there and putting out huge numbers. The same can be said for paladins, but paladins just last longer due to using plate armor and having bubble shields.2. What class do you feel comfortable dps'ing as? No matter what class is best, if you are not comfotable with it, you will not do very well.
This all depends on what you want your warrior to be, tank or dps. Tanks will always want to use a 1-handed weapon and a shield. Tanks use mostly talents from the protection talent tree. Arms DPS is somewhat for soloing. Use either sword and board (1h and shield) or two one handers, or one 2-handed weapon. It is purely a matter of choice for arms. Fury warrior will want two 2-handed weapons as there is a talent in the fury tree to use these.
It's depends on what people like, but I prefer mine as an AP so that I can take advantage of the Q skill, which can proc the Lich Bane every 3 sec and with AP her E skill also get a huge boost in damage. Also there are so many +HP item in the AP build rather than the dps build.
