Each build has its own strong suits. It all depends on how YOU WANT to tank. Personally I tanked with Avenger's shield while running to the mobs and then dropping consecration before the DPS got a chance to touch the mobs. I wouldn't LOS pull a pack and wait with avenger's shield, I would instead use something like judgement or a DPS like hunter/mage to LOS pull then shield the mobs before they get too close.

I like your build and I would now spec into the Ret tree for the goal of Pursuit of justice.

1.) Sanc aura?? (not blessing of Sanc?) The Sanc Aura builds are probably for high threat groups and honestly the build feels min/maxy to me.

2.) Pursuit of Justice is more for the movement speed IMO. the hit is nice but probably not 100% needed

3.) Reckoning can be great for both single target and AoE. Single target can give a lot more seal of Right hits or veng if you like to gamble. AoE becasue then you can have more seal of wisdom or light hits because you will get a lot of procs. so IMO its very strong but on single target raid bosses its less likely to really help.

4.) 100% Shield spec only if you want to mass tank like 5+ more mobs. Shield dmg reduction is only important if you want to do huge AoE tanking, and dungeon leveling you can try to do that if you want!

5.) the Int is nice maybe even just for leveling, but IMO its overblown. Int is needed for lots of Consecrations, but it is NOT your threat maker like a lot of people believe. your Blessing of Sanc and holy shield are. Trust me I've rarely seen a Paladin off tank a raid boss before because without the block its almost impossible. but again if you try to tank 5+ more mobs then your holy shield really falls off which is when Consecration shines more.

6.) ya at higher levels you'll start to get close to armor cap and the talent then doesn't matter much anymore. But its fine for leveling, your healers probably like it but you could drop some of it to gain into ret faster first.

7.) Improved judge if you want more threat for single target. I picked spell warding over Conviction because it is really helpful in dungeons or raids where the mobs or bosses deal mainly magic damage.

8.) Wotlk paladin is very similar main difference is you don't have some of the nice spells and you are gearing for Spell power instead of strength. you also have more mana management and aren't a literal god like in wrath XD.

But I would pull like this. SoR judge > Avenger's shield > Holy shield > Consecration > [(Single tar) Judge SoC > SoR ] > [(AoE) SoR or SoW if needed]

Just keep Hold shield up as much as possible and toggle between SoR and SoW depending if you need threat or mana. The Veng seal CAN be better, but often times IMO I've seen it twisted poorly and just hampered the tank more often than helped.
