The more I think about it I’m honestly not sure why this spec wouldn’t work out very well in PvE, sure no IB or PoM but over all it seems pretty solid for pure PvE and hell in group PvP and / or long range sniping it would still be pretty powerful.
The only two points that have me questioning it right now are these:
1) I can’t honestly see the viability of working Pyro into this build without imaging you’ll always be using 8/8 NW and the reality is it’s going to be very quickly 2 item tiers behind when 1.11 goes live. The set was amazing when BWL first when live and even today it enjoys quit a reputation with it’s incredible proc but even full tweaked out (head, legs, and shoulder ZG enchants) the set alone clocks in at a fairly ‘meh’ level of damage, crit, and hit. Long term it’s honestly not a crutch I’m going to attach myself too for PvE, though for current level PVP from 1.11 to the expansion I will probably pick it up at some point along with PoM because two back to back instant Pyro’s is a nearly unbeatable combo.
2) I’m still not sold on the longevity of fire in long term consistent damage dealing fights (Ouro, C’thun, etc.) where mana has already become an issue. Hell on C’thun the other day I used something like 40k+ mana total with spirit regen, mana potions, gems, NDB, and evo all worked in and that was using the most efficient spell we have. Master of Elements is designed to help this but I still have my doubts…
(Not going to factor in regen or all talents right now because I’m lazy)
6597 mana (my mages base) works out to be about 23 (rounding up) frostbolts, double that number assuming your raiding and used evo plus gems to regain a 100% of your mana over the course of the fight. With 46 cast and a 15% crit rate you’re around 7 crits total from 200% of your base mana pool, assuming 1k average hit (that’s pretty common these days right?) and 2k average crit that works out to be 53k total damage.
Now for Fire
6597 mana works out to just at 16 fireballs, again double that number and its 32 total from 200% of your base mana pool. Given the nature of fire we’ll assume a 21% crit rate (basically directly adding 6% based on critical mass) which equals out to around 7 total crits, this nets back another 2 fireballs with the Master of Elements talent thus giving us a total of 27 hits and 7 crits. Averaging a 1.5k normal hit with a 2k normal crit (honestly pure theory here, haven’t played fire in months) you’d come up with 40.5k non crit damage and 14k crit damage, totaling 54.5k damage.
There is a hell of a lot more things to take into consideration here for a real comparison but this is basically the math I was kicking around this afternoon. I’ll probably work back though it all with talents and everything spec’d right tonight but the picture that’s being painted seems clear to me. Frost gets the damage up front and gets it done faster (.5 seconds faster cast, talented and un-talented) while fire banks on a higher crit rate and more total mana regened over the course of the fight.
As a side note I don’t personally see the scorch build option as being a reasonable comparison to either frostbolt or fireball because of the scaling issues involved with a 1.5 second cast spell and diminished returns on plus damage gear. However in the short term with Master of Elements and the improved scorch talent you might be able to work out an extremely efficient build leading up the expansion.
