I'm looking for the overall best Tankadin build in your opinion. I have a Female Dwarf Ret Pally, that I love, but I'm now leveling a Female Blood Elf Prot Pally. This is the cookie cutter I'm using, wanted to get your opinion, and what you would do to change this:
0/53/18
Also, as a long time Ret pally, I'm used to using certain blessings and aura's for different situations. With a tankadin, what do you suggest? For 5 Mans, I'm assuming Blessing Of Kings, Devotion Aura, and Seal of Light(for health regen) or Seal of Just curious as to what you use in 5 mans vs solo'ing to level. I'm going straight Prot Pally all the way to 80 with my Blood elf.
In my opinion, my tank build would be: 0/53/18
It's not very much different from yours, but I would take 2/2 Imp Judgements, 2/2 Pursuit of Justice, and Seal of Command. 2/2 Imp Judgements is not strictly needed, but sometimes it's useful to have your Judgements available a bit early. The 969 rotation is the standard, but don't get tunnel-visioned. Sometimes deviating from 969 is necessary. For example, if you were kiting a mob, you'd prefer to have more Judgements.
As well, I am a great fan of Pursuit of Justice. I find being able to move swiftly is very useful, and I think trading 2% crit is worth it. However, a lot of other paladin tanks would probably disagree with me, and say that having Tuskarr's Vitality on your boots is good enough.
Seal of Command is very useful on trash and adds. It's especially good for AoE tanking.
I'm not sure about Divine Sacrifice. I'm not sure how much you would use it as a tank. You might be better off just getting 3/5 Divinity instead. Divine Sacrifice is powerful, but if you never use it because you're always tanking, better to take something else.
As for Auras/Blessings/Seals, at low levels I would suggest Blessing of Kings, Devotion Aura, and Seal of Righteousness. Don't use Light, let your healer keep you healed up. When I see low level paladin tanks running Light1 I know that the tank is going to have a hard time holding aggro.
Switch to Blessing of Sanctuary when you get it, and then Seal of Vengeance or Command when you get those.
1 Or worse, Seal of Justice. I'm not sure why Justice is so attractive to newbie tanks.
