My Paladin Respec

[Tal]

I've been pondering a respec on Sharanna from 31 retribution/21 protection to holy/retribution. But as I look at the talents more and more I just can't make that leap to going cleric. Though I do admit there are times with more healing oomph would really be helpful (most noticeably chain healing Gnolack last night at the General, twice to OOM and finally applying Lay of Hands on him). So I'm considering the following respec:

Protection
Redoubt - 5 points
Toughness - 5 points
Improved Seal of Fury - 5 points
Shield Specialization - 5 points
Reckoning - 5 points
Holy Shield - 1 point

Total Investment - 26 points

Retribution
Improved Blessing of Might - 5 points or Benediction - 5 points
Two-Handed Weapon Specialization - 5 points
Vengeance - 5 points
Seal of Command - 1 point
Anticipation - 5 points
Improved Retibution Aura 3 points
Consecration - 1 point

Total Investment - 25 points

I'm thinking that this setup will maximize my power to defense ratio. One of the question this boils down to is Blessing of Might (which I rarely use as I need mana to regen during fights) versus Benediction (reduces cost of Retribution skills by 15%). As my main mana hogs when tanking are judging Seal of Fury, consecration and holy shield this seems marginally helpful versus Blessing of might.

Thoughts?
