Holy/Ret Specc level 48

This gives you good damage and movement and killer heals!

Hunter Leveling/PvP Spec

This is the spec I used until 40. It gives good ranged crits and speed plus a better beast. I respecced to all BM after 40 so I could have Bestial Wrath. Now I'm filling in marksmanship again.

Warrior Spec

There has been and will continue to be a rivalry between those who like Arms over Fury spec. I am in the Arms camp. I like Fury too, after you fill out the arms side to Mortal Strike!! Don't take Tactical Mastery until level 30. Any warriors first 5 points should be in Cruelty then go Arms. This goes to level 40, more later!

Rogue Leveling Spec

This is a Combat oriented leveling spec. You could swap 5 of Master of Deception for the 5 in Dual Wield Specialization for a little more stealthiness, but I wouldn't...or more Lethality which is a good idea.

Leveling Paladin Spec

This spec allows for fast movement, hard hits and healing during a fight without a bubble. The Holy side is optional, but can save your butt!! This goes up to level 40. The key here is to use a 2h weapon and use the following spell chain. Seal of Command, Hammer of Justice, Judgment, Seal of the Crusader, Consecrate. It will take practice, but that maxes your damage. I would then go Seal of Righteousness then Judgement again.
