So, I've been playing a shadow priest for some time now, but haven't ever gone up to VT due to my weird need to play a tweener heal/damage role post-BC. My question is, what kind of returns are you seeing with regards to mana? I'm thinking to myself that with the ~+500 damage that I have, and my MFs doing somewhere in the low 400s per tick with SW fully stacked, that if I were to have SW:P up already and just pumped out MFs that I might be able to get 4.5 MFs out before the 15 second DoT clears. So my fuzzy math is telling me that:
4.5 MF = 1200 damage*4.5 = 5400 damage
SW:P (4 ticks) = ~1600 damage
For a total of 7000 damage. 5% of that is 350 mana. Is that really it? That's not even a fireball for a mage. Is there a CD on VT, or can I just go slap-happy on it and throw it on every 15 seconds?
Enquiring minds want to know...
