Raiding Minimums for Naxxramas-10

As expected, I wound up looking for a PUG for Naxx-10 this morning instead of running with GoV. More on how that turned out later, but on reflection I'd like to put down what I think the minimum values for Naxxramas raiders should be.

Tanks
20,000 HP minimum, and of course more is better.
Defense capped (540).
Avoidance as high as possible without sacrficing Defense or STA.

Healers
14,500 Mana minimum. Again, more is better.
1350 spellpower minimum. But if your healers only have this much spellpower, take 3 healers and beef up your tanks and dps.

DPS
1,200 DPS minimum. We wiped repeatedly in the Plague Wing due to one DPSer bringing only 900 DPS to the table. 1,200 DPS will ensure that bosses go down before healers' mana pools empty completely. And of course, more is always better.
