Mograines Might is better.
Are you macroing your Holy Avenger with Lifeblood and Jade Charioteer Figurine?
Use your coins from dailies on Sha and Normal raids. NOT LFR. Unless it's Elegon.
I can't comment as you didn't provide a WoL kill but; a common mistake Paladins make is that, they don't use Exorcism over CS/TV. Remember you can get upto 5 Holy Power and it will not fuck up your dps.
Glyph of Harsh Words
Glyph of Double Jeopardy.
Definitely swap out Glpyh of Avenging Wrath - the heal is pitiful. Swap that over to Double Jeopardy, it's usually a safe bet. WoG isn't bad, but you'll want to consider Mass Exorcism if you can get to Garalon/Mel'jarak (especially the latter of those two).
