The Wisdom of TankSpot posters:

"Talking as a pure tankadin, drop all of your major glyphs and replace them with Divine plea, Spiritual attunement, and(debatable for RD) Divinity. As for the minor ones, you should get glyph of Blessing of kings, not might. As for talents, you definitely need benediction, since all of the spells that you will use are all instant cast and it will help you hold threat longer. you can get the points you need for the full five by dropping heart of the crusader and the improved divine sacrifice. Also, Pusuit of Justice isn't very useful for tanks, pick up stoicism instead. Stoicism will allow you to get out of stuns and continue building threat as opposed to PoJ giving you a little more dps while not effecting your tps."

"For Raiding Judgement of the Just is a waste of points spent for a seroius raid tank."

"Now, I'm sure you know that shield block = Guaranteed avoidance, while Parry and Dodge isn't always going to happen."

"Generally, Warrior and Paladin tanks' threat is built off of their shield block rating. Your armory page tells me you have 12% shield block rating."

I also notice that the only TankSpot posters who actually provide sources/math to back up their claims seem to be Maintankadin veterans. :)
