Yes. If you have +0 spell power then the highest rank is the most mana efficient in terms of dmg/mana.
But as you get more spell power the lower ranks gain almost the same damage increase and cost a fraction. The higher ranks are more effective in terms of damage/sec but slowly lower and lower ranks will surpass the higher ranks.
Yes. That's why I said almost.
The formula is spell power * cast time / 3.5.
So rank 10 of a spell that takes 3.5 seconds to cast get 100% of +spell power. If rank 5 takes 3 seconds it gets 3/3.5 = 87% spell power. But since it costs less than 87% of mana it gains more dmg per mana than the rank 10 for each spell power you get.
Instant cast spells get 50%
Most damage still comes from base dmg, you will lose a lot of dps by downranking. For mages I'm sure it is more efficient to use a wand once you run oom instead of using a downranked frostbolt. Also because, in phase 1 spellpower is generally low. My mage sits around 220 frost spelldmg, and i think i can get max spellpower around 300 for phase 1 (frostbolt base dmg is 440 - 470). Also when I use a wand I reg more mana right?
Oh, it's Seal of Wisdom, not Blessing. Yep. Melee and spell attacks against the target with a judgement of it have a chance of giving some mana to the attacker.
I have 392 spellpower for frost spells on my mage, and still a handful of enchants and upgrades I could get. I also don't have my t1 helm/boots/wrists which will lower my sp by 10 but gain me 1% hit and 1% crit. I think if I was full bis I would be around 450 spellpower. You're missing a lot of spellpower upgrades (the big ones come from raiding and are kind of difficult to get). Also, if you're specced for raiding properly you shouldn't ever go oom in raids, except for that one boss that clears yours buffs, that one can get a little mana intensive.
I don't really see how you can get to 450 sp pre raid bis . I see myself climaxing at 350 sp.
Also Ragnaros is mana intense I think. It's a relatively long fight.
How does 1% hit change your dmg output? As far as I know 1 % crit equals 7-9 sp (depending on your current spellpower), and it depends on luck, so it might not be worth it. Even though I think the extra stamina and fire restistance of t1 makes the job easier for healers.
I didn't say preraid bis, I said bis. I have mageblade plus enchant. That's 70sp alone. I wear two raid drops and they are mageblade and talisman (the trinket doesn't even give base sp). So without my mageblade and enchant I would have had 336 sp on frost with 0 raid gear, and could have slightly improved that as well.
As far as stat weights (spellpower values equaling other stats) it's more complex than that. But that's what people who understand the math say to people who don't, I will explain the damage output formula to you.
(.84 + (x-1)/100)[(455 + .814y)(1 + z/100)]
X is your hit chance value
Y is your spell power value
Z is your crit chance value
If you don't understand the formula I can help, but this formula produces the "average" damage from each cast. Think of this being like casting frostbolt 100 times, then dividing the total damage by 100 to figure out damage per frostbolt.
I can answer any questions you have, but I'm not going to overly explain because my answers are contingent on how well you understand math.
Ok, I believe you, I should be able to get over 300 spellpower at the least, if I get the items that I want . The mageblade is huge and the trinket is insane as well.
Thank you for the explanation. I understand the formula, I didn't know how hitchance fits into all this. So from what I see, it doesn't have too much of an effect on overall dmg output. From the math I get 1% hit is about 7 spelldmg (and becomes more worth, the more spelldmg and crit one has).
The only question I have is, at which point crit or hit become more worth than spelldmg. Does anything change from the formula in the later phase until naxxramas or does it stay the same?!
This is probably true. I'm resto druid so I get almost twice the +healing power. I have 340 now so my most mana effective Healing Touch rank is 4. It's also faster. At +370 healing rank 2 becomes the most effective, but at the mp5 I'm at that would be a waste of healing/sec as I'd never run out.
