I am trying to figure out the best build for my 3x ret paladins for max dps.

Should I focus on spell damage for my ret paladins? considering all there dmg really are spells, or should I focus on str, agil for crits?

Also on my prot paladin, I should focus on armor, sta, str, agil right?

I need all the help I can get, I am trying to maximize dps on my toons, if you have any advice please let me know.

Also this might be weird, but is it normal for my prot paladin to out dps my ret paladins by double there dps?
