Eh I'm a fire lock = Ayamai(blackhand server)
This is one of many ALTs though and Definately my least played, but I've done kara plenty and some gruuls. and easily first on Dmg by a considerable amount(ALWAYS first by 500K, sometimes up to a million in kara, THOUGH I attribute that completely to other players sucking more than myself being good.)
Why am I a fire lock?
1: Because I like it. I Love fire spells, and it's my character. I find spamming SB to be boring.
2: Okay so if you're destro(0/21/40) and fire You get :
Emberstorm: Increases the dmg done by your fire spells by
10% Sacrifice imp: Increases the dmg done by your fire spells by
15% Curse of elements: Would increase your fire dmg to the target by
10% IF there's a scorch mage (With is stacked to the maximum) Fire dmg
+15% Fire warlock doesn't Have anything equal to IMP SB To support other classes
Scorch mage gives Fire warlock more dmg from imp scorch
Shadow priests provide 5% spell dmg from misery
Potentially can get Fire Spells dmg done to target increased by 55%
If you're Destro 0/21/40 and shadow:
Imp shadowbolt : 20% Shadow dmg done to the target Lasts 12 seconds or 4 sources on Shadowbolt crit
Sacrifice succubus : 15% shadow dmg
Curse of shadows : 10% Shadow dmg
If there's a shadow priest (Shadow weaving x5)
10% shadow dmg
+5% misery
SB warlocks Give shadow priests more Dmg from Imp SB
Shadow Priests give SB warlocks more Dmg from Shadow weaving/misery.
Potential to increase shadow dmg done to target by 60%
Okay so
There's a 5% difference in the two specs..
HOWEVER
You need to crit to proc 20% from Imp SB (Which means it will be on the mobs Almost all the time, but still the fire dmg bonus will Always be there no matter what
Note that the destruction tree has
THREE Spells that specifically relate to shadow Dmg
(Imp SB, Shadowburn, Shadowfury)The latter of two which are not going to be spammed.
and
FIVE That specifically help Fire spells(Improved immolate, Emberstorm, Conflagrate, Improved Searing Pain, Pyroclasm). Once again the latter two arent so useful.
TEN That help both fire and shadow, However
Bane: 2 fire 1 shadow
Soul Leech: 4 fire 2 Shadow
These talents affect more Fire spells than Shadow.
Also note that the Tooltip on shadowbolt rank 10= 482-538 dmg
And on Incinerate rank 2 = 442-514 (Plus 111-128.5 Dmg if affected by immolate)
So 553-642.5 ALL while Immolate is ticking on the mob.
Also conflagrate itself is 579-721 instant dmg if the target is affected by immolate ( Best used when immolate is almost up)
Shadow destro lock = Spam SB
Fire Destro lock = Immolate -> Incin Incin Incin ->Conflag (Soul fire when you want)
Overall I think they seem pretty equal..Fire gives you more spell options than SB which is mainly why I chose it, and obviously destruction tree has more talents which affect strictly fire spells, so that seemed like a good decision to me.
Now I'm not good at math I'm not going to start saying which is more DPS and all that. Just from my experience in the lower raids Fire destruction seems to be Underestimated.
If I messed up something in my post sorry it's 8AM and I haven't slept
