Quick thoughts on the Ret Pally discussion:
Now, I fully admit that the Ret Pally in my guild is probably not typical of alliance Ret Pallies, but using his numbers as an examination of the potential of the class, I think it's pretty easy to argue that an Alliance Ret Pally justifies his raid spot. Working off the WWS of our kill (located
here), we make the following estimates of the damage generated by our Ret Pally friend Draynam:
1) His personal DPS was 1681.
2) He was in a group with Rodemboo, Sydric, Shifft, and Gcjr; hence, 2% of their damage can be credited to him via Imp Sanctity Aura. The combined DPS of those 4 players is almost exactly 8000 DPS; 2% of this is another 160 DPS to add to Draynam's total, bringing us to 1841.
3) An additional rogue in that group would have generated about 2200 DPS; hence, the 3% crit aura must account for at least 350 DPS to justify his raid spot. Given that the DPS total is around 28k, this basically says that a 3% crit damage buff must increase raid DPS by at least 1.2%, which is pretty clearly the case (given that the buff to the rogues alone is over 150 DPS).
Conclusion: if you have a good, well-geared ret pally, they are a definite asset to your Brutallus raid. If you don't, then you're better of bringing a more conventional DPSer.
