(did you know in your FAQ you guys never really come right out and say- LEVEL WITH THIS BUILD)...
While not giving a link to the build, I list out my recommendation for leveling in terms of talents below.
2.2.2 What talents should a Paladin be getting as he levels?
Again, it depends on which of the methods above you want to do. My personnal recommendation for single-target grinding is to first move up retribution, grabbing Benediction, Imp. Judgement, Imp. SotC, and then SoC. After that, move up Holy, getting Divine Strength, Spiritual Focus, Healing Light, next 2 whatever, then Illumination, and Divine Favor. Once you have DF, there is almost no downtime between pulls. After this, you can move down holy to get holy shock, or you can start moving down Ret towards CS.
At level 61, I did this, but you don't have to. I respecced to 10/31/11. This gave me SF, Reckoning, HS, and SoC. I gave up my DF, but I gained the ability to tank in instances, and by myself I was able to put out more dps, especially when Reckoning would proc, giving me usually 3 hits (2 normal and 1 SoC proc), and still keep my uninterruptable heals.
For AOE grinding, just get talents that you would get if you were tanking, the only exception being that SF can be a good investment, though not required. Get Redoubt, Anticipation, Toughness, Shield Specialization, Imp. RF, BoK, Reckoning, BoSanc, HS, Sacred Duty, One-Handed Weap Specialization, Imp. HS, Ardent Defender and Avenger's Shield.
