Maximum buff vs minimum diversity

[Iru]

Given the lack of physical DPS in that list, which minimises the value of the 10% AP buff, what's your thinking behind including a Hunter? Is it solely for replenishment (i.e. SV)?

If it's solely for the provision of physical damage then I think a third shaman or a rogue might bring better utility.

In addition, I'd go Disc over Holy for the priest. Penance & PW:S are ungodly.
