Many people are having trouble with mana on General Vezax, and very often a problem on the boss is healers going oom. But, holy paladins have one very effective thing they might do. The retribution talent Judgements of the Wise restores 25% of your total mana. And this works!
As you might see on my example of talents you can have both Holy Shock and Lights Grace, at the same time as having unlimited mana! Only bad thing is that you must stay pretty close when judging.
Have fun topping healing meters on Vezax with your pvp holy spec!
<<<<Remember, you don't have Beacon of Light, so this works best for MT healing>>>>
