A little bit of follow up data that I posted to my guild site about some real world testing on the pre 2.1 Lightning Capicator (data is from
http://www.lossendil.com/wws/?report=k6kycgi5m4egy&m )
We are pre SSC so my gear is lacking a bit in the +to hit dept which is why my miss % is high. Sephtin is a full frost mage.
Please excuse the somewhat awkward style, as it was previously only in our guild forums, but I figured the info was worth sharing:
Post 1 -----------------
Well, here's some real numbers from last night. I believe Sephtin and myself both had it equiped for the entire raid?
Sephtin had a total of 211 crits on spells that can proc the Cap. Which means he should have had 70 procs.
He actually had 62 Cap procs. (1 was missed)
I had a total of 303 crits on spells that can proc the Cap. Which means I should have had 101 procs.
I actually had 93 Cap Procs. (including 14 that missed!!)
Means I lost out on roughly 8% of the procs because it happened to proc when the mob was dead before the bolt could land.
The average Proc (when not resisted) hit for 782 for both Seph and Myself. Factoring in misses, the proc was worth:
Seph: 769 per proc
Me: 667 per proc (my hit rate sucks now)
So real world expectations should be roughly each crit is worth:
Seph: 769 / 3 * .9 (for when mobs are dead) = 230.7 This will go up with the slight buff.
Me: 200 each crit.
Post 2 -------------------
So what does it mean?
For seph, it's worth roughly:
Frostbolt spam: 29% crit rate: 230.7 * .29 = +66 damage.
It's a bit hard to compare to a regular +66 damage trinket, because its a flat +66 damage. It does not get doubled on crits, but it does not get nerfed by the frost bolts damage coefficent (.87? then another 5% hit).
Just a rough guess, but a +66 damage trinket would be worth on frostbolt spam:
66 * (Deep frost mage's frostbolt recieves 73.26%) .73 = 48.18 damage. Plus the crit value of 66* .29 = 19.14.
So roughly 67.5 damage. Would then need to factor in things that add to this damage that do not also effect the Lightning Cap proc (CoE, but not misery). So maybe another 6 damage up to 72 damage.
Frostbolts coef which looked really low to me came from:
http://www.wowwiki.com/Spell_Damage_Coefficients
Since the Lightning Capicator is valued after taking into accounts Resist and Partial Resist, have to finally tack that on to the above value.
Seph has an average miss rate of only 1.3%. So the final value would be 72 * .987 = 71.064
For me,
Fireball spam: 200 * .32 = 64 damage. Same as above, hard to compare to a trinket, but here's a shot:
A regular 64 damage trinket is worth: Fireballs receive .90% from +damage (assuming improved FB) = 64*.9 = 57.6.
Crit is ugly considering the mob has to stay alive for the ignite to tick, but lets assume it does:
Crit is then worth an addition 1.1 = 57.6*1.1 = 63.36 * Crit chance .32 = 20.2 for a total worth of 77.8. Same as above, have to factor in debuffs on the mob that do not effect the Lighting Cap (Scorch + CoE) would add another 10% or so damage (scorch is not always up) ~ 89.5.
Now have to take out misses and partial resists. Last nights resist numbers where through the roof considering we had new Gsoul playing 1 of the 2 warlocks and CoE was hardly every up.
My miss rate was 8.1 (bad mage!) for fireballs, which gives us 89.5 * .919 = 82.5. My partial resist mitagation was another 4.3%. 82.5 * .957 = 78.9
So a regular +64 damage trinket is worth +78.9 damage when spaming fireballs with my current gear/ build.
Scorch spam: 200 *.32 (should be higher, but test data is small) = 64 damage. 64 * .4286 = 26.88. Working crit the same way as above:
26.88 *1.1 = 29.5 * .32 = 9.44 for a total worth of +37 damage. Work in the debuffs and it would add in roughly 4 more damage for roughly +42 damage trinket. After resist rates and partial resist, its worth roughly 37.8
So in summary, the Lightning Cap is worth a flat +64 damage to me no matter what spell I cast. If I'm just spaming fireballs, to replace the Lighnting Cap i would need a trinket that is +53 Damage.
When spamming Scorch, I would need a trinket that is +109 Damage to replace it.
If I only spammed one of the two spells, it's a no brainer, but I use both.
Side Note:
For seph, he needs a +62 damage trinket to replace the Lightning Cap when spaming Frostbolts.
----- The above post was for the trinket < 2.1 It'll be worth slightly more in 2.1 (today!!) and the value will go up a good bit more as my +hit increases.
