I was sitting and wondering how a shadow priest would do in PvE at lvl 70. So I figured I would do a rough comparison with a frost mage just using frostbolts. This is in a 25 man raid, not in the same group. 2 min of pure dpsing on a boss.
Mage
700 spell damage
Talents:

Using:
48*Frostbolt (Rank 13). Costing 13464 mana and doing ~93,3k dmg accoring to my rough calculations (~780 dps)
Shadow priest
500 spell damage (I don't dare to think yet, that priests will get as much spell dmg as mages)
Talents:
http://www.worldofwarcraft.com/info/...10051123051051
Using:
5*SW:P (Rank 10). Costing 2875 mana and doing 10740 dmg(with only the spell dmg as modifier)
8* VT (Rank 3). Costing 2125 mana and doing 5950 dmg(with only the spell dmg as modifier)
8*MB (Rank 11). Costing 1913 mana and doing 5187 dmg(with only the spell dmg as modifier)
29*MF (Rank 8). Costing 5684 mana and doing 29812 dmg (with only the spell dmg as modifier)
Total 12597(-4342=8255) mana 86850 dmg(with all the modifiers) (~720 dps)
Now here comes the twist: Vampiric touch. Vampiric touch and VE gives the priest and the rest of the group 4342 mana and 26055 hp. Lowering the priests total mana cost of all spells to 8255.
My calculations are rough, I know, but they still prove a point imo. I'm no mage expert so if any mage has a better suggestion on use of spells and talents, please tell me.
My question here is: Will these sort of things bring shadow priests more into PvE then atm? Since the mana does not seem to be a problem for a shadow priest. Since everytime I mentioned a shadow priest in PvE all I heard was: Mana inefficient, mana inefficient and so on. Even if I have made some small misscalculations or that my talent speccs aren't perfect. I still don't think that fixing that would make up for the amount of mana and thereby dps a shadow priest would give to his group and raid. (This is from my PoV on the shadow priests in end game PvE atm)
