Best PVP Disc Priest CR?

As the title states, I am leveling a Disc Priest. What is the best CR to use for PVP? (Arenas/RBGs)

I have looked at Oracle II, Gladiators, and Richie's Salvation.

Thanks guys.

 

Gladiator Suite - Priest, hands down. Can be a bit tricky to set up though and requires you to learn how it works/what all settings do.

 

Thanks man. I will keep it in mind.

Any other opinions?

 

I swear by KingWoW Disc ... I find it better than gladiators, but it may be a preference thing; I also have no issue setting up either CR.

Salvation hands down
