Hey there.
I myself is not really the math genious out there, but I've been a reader of the forums for quite some time now, and found alot of useful information form the regular posters.
Now, this might seem like a dumb question, but I'm only trying to understand :)
From your other thread "Some mage theory", you posted this little bit:
With Missles, but using R4 Frostbolt (2.1s cast, for a 25.4s "block"):
Damage:
9*(78+648*(2.6/3.5*.95))*1.19*(.83+.07+.112) + (230*5+554)*1.13*(.83+.07+.112/2) = 6,777
Mana usage: 9 * 56 = 504
Mana returns:
Spirit: (224/4+12.5)*0.3*25.4/2 = 261.0
MP5: 61.6*25.4/5 = 312.9
The other two terms are the same.
Total: 1082.8
DPS: 266.8
MPS: +22.8
Now, I assume the usage of the Rank4 frostbolt actually regenerating mana for you is dependent on some things. Of course to achieve the 2.1s cast time you would have to be speccing Imp. Frostbolt, and Frost Channeling to get the 56 mana bolts. With those 2 things taken into consideration, gear must also play a part in this.
I currently walk around with a gear setup which gives me 185 spirit, 17/Mp5 and +443 Frost dmg.
The thing is, I recently respecced from frost to a 15/33/3 build, so I don't have either of those talents to deal with.
My question is, can this "trick" be done somehow with my current build / gear setup, or does it rely too much on the lowered casting time and 15% less mana cost to ever be efficient enough compared to just wanding? I'm thinking about keeping up a "steady" dps whilst regaining mana on certain fights, even though my mana isn't getting burned that fast since I'm spending quite some time doing my best to keep ignites rolling.
