My Paladin build

Please offer advice, especially in regards to my talents

Heat, you shouldn't worry about going healing spec, for now at least, although it is none of my concern as to what spec you go into. Since your concentration is in the Holy Tree. What I'm posting is in theory.

If, your a holy spec, this MIGHT be the way to go. Just seek the opninons of others as well, since i do not know a whole lot about paladins. (I just used the build you were currently running through and expanded on it)

This would be a good retro leveling build to 40, i especially like the Pursuit of Justice talent, its a good "OH SH--" escape or to chase down runners.

If you are looking to do some tanking

I decided to do neither, and went 100% holy...so much for me taking advice!

With all the armor I have( even without my 1500+ armor shield), I can heal pretty well, and tank too!
