Gear looks ok for the front of ICC. Sindy/LK might be rough. Go to maintankadin look up their spec recommendations. Yours is off a bit. Glyph of Divinity is silly. Mana shouldn't be an issue. Not to mention if YOU are using LoH, someone isn't doing their job. Dazing Shield is PvPish. Use Focused Shield (for single target), Ascetic Crusader, and Divine Plea (which when popped gives you insta 3HP). Can't tell your Primes from the Armory, but they should be: Truth, HoTR, and Crusader's Strike. SotR is decent as is Judgment. All IMHO.
