My first entry, feedback is appreciated.
If you don't like the 61 Purifier but still want to shield your Tank (and some group heal) i have the following build for you.

28 Sentinel / 40 Purifier / 8 Warden

Legendarys

Sentinel:
- Bolt of Light
- Banish

Purifier:
- Flame Lance
- Flash of the Phoenix

Warden:
- Healing Flood

Masterys
Righteous Protection(1)
Divine Inspiration(3)
Supplican't Haste(4)
Faith's Reward(1)
Divine Favor(1)


Buffs
Wisdom of the Ages
Sign of Anticipation
Heroic Resolve
Marked by the Light
Healer's Blessing

Healer's Blessing is better than the shield from Caregiver's Blessing

Playstyle
Eruption on Tank
keep up Flame Lance and Bolt of Light (if possible)
3 Stacks Healing Flood
use Spam Macro on Tank or target that needs it
when group heal needed use Overflowing Renewal
