Need some theorycrafters/spreadsheet pro's

[mightycerberus]

okay ive been doing the felguard spec since patch 3.0.8 and love it, i can do an average of 5k dps with my more than decent naxx 25 gear.

My current spec:

My spec change suggestion:
http://www.wowhead.com/?talent=IZ0tIzsxRq0sgzZVchVrzuc
or
http://www.wowhead.com/?talent=IZ0xIzsgMq0sGzZVchVrzuV

so what i want is the fel synergy, for those fights like sartharion and sapphiron, where he just need a bit help with his keeping up his HP.

what i want to know is which of the two would be there better, what "in theory" would be the best dps spec of the two, would there be a dps loss/gain to this spec.

an addtional question would be if the 13% chance of stun on rain of fire (for the trash/aoe pulls) would be a good idea, and maybe a little help for the tank? (im not very fond of shadowburn and find this a somewhat useless ability during raids)

a last thing to add is if you wish to add a third similar spec with a few differences that may be more ideal, feel free to link it, with youre added argument for it being better/more ideal.

things that are possibly needed for the spread sheet work:
4 pieces of T7 valorous gear (Shoulders, legs, robe and gloves)
Trinkets: Dying curse and Sundial
~1700 SP
~25% crit
~340 hit
~550 haste

as said, i'm not very good with spreadsheets, so any help is appreciated.

I doubt any1 is very fond of shadowburn these days, but I still reckon that it is a better choice to fire on those "almost dead mobs". At least it will benefit you more than a 13% stun chance on 4 spells, of which you will never ever find yourself using the 3 of them, not to mention that when the trash actually matters, they are usually immune to stuns.

Fel Synergy is hardly needed. They fixed Avoidance for Sapphiron so JoL alone will prolly keep it alive. Just keep it on "your" side, cause it runs behind after airphase (where he can continue dps as well). Manage your pet on Sarth so he doesnt take churns and fissures and you won't have any issues there either, not even with 3 drakes.

I, like most other locks, would recommend Affliction of this specc if your gear can carry it, which it seems able to. But if you insist, i'd prolly go with http://www.wowhead.com/?talent=IZ0xIzsgRV0sxzZVchqr0uV instead of the two you posted.

Can anyone confirm this?

i would also like to see the notes to the fixes of it.

on the affliction thing: i'd rather not be affliction, i'm not very fond of affliction in general, i know i can do 4-5k+ dps with the felguard, and just want him to survive without having to do too much pet management. this not because i dont want to take control of him, more that i consider it downtime having to pull him away from sapphiron and sartharion when they are engaged.

Getting ur felguard killed on sarth is pure ur own fault, bind follow to a key and use it asap a firewall is announced and u should be fine to get the vanquisher title with ur pet alive at the end of the fight!
