In raids I normally run Sacred Shield, SanW and Seraphim unless specific mechanics do not allow for it.
Sacred Shield and Eternal Flame have similar output to each other. However, Sacred Shield doesn't cost any holy power to use and is an absorb, so by nature is better as you do not require to be injured to get the advantage of it
Because I run Seraphim, using Divne Purpose for me is nearly pointless because alot of my holy power goes onto Seraphim, which doesn't proc Divne Purpose, so because of this I run SanW for the steady holy power income it gives. I also dont feel I have enough haste to run DP, unless I am using EmpS
I am not a big fan of Empowered Seals, realistically you can only keep two buffs up at once, so you normally have to sacrifice using Insight or Truth, as you will always want the buff from Rightousness. Where Insight is a gain in survival over Truth, the dps difference is pretty big and dislike having to choose between the two
As such I normally pick one of the other two talents
