WHM dps VS. SCH dps

[Rewind]

With regards to 2 vs 6 minutes, as a WHM I dps for much longer than 2 minutes, if that's where you were going with that. I think it also may depend on the healers play style.

Yes....it also depends what fight we're talking about.

I can't find the numbers for energy drain for level 60 but -

Shroud of Saints restores a static amount of MP, based on player level. (707 MP / 3 Seconds @ Level 60) (180 Second CD)
You have to time shroud correctly to get all 5 ticks, so in general most WHMs will restore 2828MP

Assize restores 10% of own MP (90 sec CD) (Approximately 1300 @ ilvl195)


Energy Drain restores a static amount of MP, based on player level (I think this is 900 MP per drain, 3 drains every 60 seconds)
Aetherflow restores 20% of your Max MP. (Every 60 seconds) (Approximately 2600 @ ilvl195)

Inherently SCH is going to "last longer" because overall it has short CDs on their MP management than WHM. So with no other external source of MP regen WHM will run out of steam faster than SCH.
