It doesn't sound like you're talking about speed runs, but I'll mention this anyways.

What I do for each pack of mobs:
1. Always Stoneskin the tank at the start of the dungeon, and right start casting it again right as the last mobs of each pull are almost dead.
2. At the start of each pull cast Divine Seal
3. Cure 2 the tank
4. Regen the tank
5. Medica 2 the group
6. (If necessary) Cure 2 tank again.
7. Use Cleric stance
8. Holy spam (at least 4)

With the stun effect of Holy you wont have to throw out any more cures if the group is properly geared. This is helped by the DS regen and medica. An awesome PLD taught me this method and it works amazingly. This, and only this is how sub 10 minute WP runs are possible.

Just be sure to have Shroud ready because as I'm sure you know multiple Holy's (Holies?) pull a lot of hate, and us whms are squishy!
