My guild is currently pounding through BT at a phenomenal rate and there is an inner argument regarding what the best classes are to combine with Shadow Priests. The raid leaders and officers are ranking it in the order of (regarding most important to get a shadow priest to least important):

1.) Mages
2.) Hunters
3.) Elemental Shaman
4.) Any DPS class with mana that isn't a Warlock
5.) Warlock

My argument is that we are wasting a large amount of a Shadow Priest's utility (in the health regen) grouping them up with classes almost exclusively other than warlocks. Their argument is that we can Life Tap and Dark Pact.

I'm wondering if anyone has any information on this topic, regarding which class is the best to combine with Shadow Priests. I've tried using the search function, and have yet to find anything that I'm really looking for.

Thanks,

Pre
