Elemental ShamanのDPSに関して

EUのShaman Forumで実際に計算式を用いて

Blizz側が検証を行った興味深いポストがありました。

ソース



スレ主はLiveとPTRでdpsを計測して
6.2%のdpsが減ると検証しました。

Live
Test runs: 7
Total test time: 764 seconds
DPS: 1041.7
Crit rate: 35.4%
Castes per minute: 31.3

PTR
Test runs: 12
Total test time: 1219 seconds
DPS: 976.8
Crit rate: 37.2%
Castes per minute: 34.4
これにTharforがDPSを計算して検証を行っています。
Lightning bolt (Rank 12) has a cast time of 2.5 seconds and deals 563 to 643 damage.
(http://www.wowhead.com/?spell=25449)
The average damage of Lightning Bolt therefore is 603 (563+643 divided by 2); let’s call this 600 for talking sake.
LT Bolt (R12)は2.5secで563-643 damage。
平均すると603damage、わかりやすくするため600とする。

The old Lightning Overload talent, with 5 points spent, gave a 5% chance to duplicate the spell cast exactly, right?
So in every 100 casts, 5 of them would be duplicated.
100 casts of a 600 damage spell = 60,000 damage
5 ‘procs’ in that 100 casts would deal an additional 600 damage, so 5*600 = 3000.
The total damage dealt in 100 casts would be 63,000 damage.
100 casts of a 2.5 second spell = 250 seconds.
63000 damage / 250 seconds = 252 damage per second.
現状のLO(5/5)は5%spellを倍にする。
100 castで5回は倍増
100 cast x 600 damage = 60,000 damage
LOの5回分= 600 damage x 5 = 3000 damage
Total damage = 63,000 damage
100 cast、2.5sec = 250sec
63000 damage /  250 sec =  252 dps


The new Lightning Overload talent, with 5 points spent, will give a 20% chance to deal 50% damage again:
So in every 100 casts, 20 of them would do half damage (300 average).
20*300 = 6000.
The total damage dealt in 100 casts with this new proc rate is 66,000 damage.
66000 damage / 250 seconds = 264 damage per second.
264 / 252 = 1.0476 – a.k.a 104.76% or an increase of 4.76%.
新しいLO(5/5)は20%の確立で50%damage増える。
100 castで20 castは50% damage (300 damage)増える = 20 x 300 = 6000
Total damageは66,000 damage。
66000 / 250 = 264 dps
264 / 252 = 1.0476、104.76% または 4.76%の増加

This obviously ignores crit chance and spell damage gear and only looks at the Lightning Bolt in its’ purest form, but to me it seems clear that the base DPS is mathematically higher with the changes.
これはLBのcrit率とdamage bonusを除いたLBの純粋dpsです。

Under the old system, assume maximum damage dealt each cast (643).
100*643 = 64300
5*643 = 3215
Total Damage = 67,515
Damage per second = 270.06
現状でmax damage(643)で計算すると270.06 dps

Under the new system, assume minimum damage dealt each cast (563).
100*563 = 56300
20*281.5 = 5630
Total Damage = 61,930
Damage per second = 247.72
247.72 / 270.06 = 0.9173 – a.k.a. 91.73% which shows a DPS drop of 8.27%.
PTRでminimum damage(563)で計算すると247.72 dps
247.72 / 270.o6 = 0.9173、91.73%、8.27% dps 減少。


This proves to me that because each spell does not have a fixed damage value, but instead has a damage range, that there will always be an error margin; for Lightning Bolt rank 12 that appears to 8.27% variance...
Spell自体は固定spell damage値がないのでdpsに幅が出る事を考えると、この8.27%がdamage幅と考えても良いと思う。
続いてスレ主のbonus damage(865)を参考にdpsを計算しています。
With a 2.5 second cast time (base), the spell damage contribution is 71.43%. Let’s use Mmootimus’ Armory profile (since this is his thread) and take the spell damage bonus of 865.
0.7143*865 = 617.8695 added damage per cast.
So each cast at 2.5 seconds is now 1217.8695 damage.
100 casts = 12,1786.95 and 250 seconds = 487.1478 damage per second.

2.5secの場合damage bonusは71.43%。
0.7143 x 865 = 617.8695 damageが1castに追加。
2.5secだと1217.8695 damage。
100 cast = 12,1786.95 / 250sec = 487.1478 dps

With a 3.0 second cast time (base), the spell damage contribution is 85.71%.
0.8571*865 = 741.3915 added damage per cast.
So each cast at 3.0 seconds is now 1341.3915 damage.
100 casts = 13,4139.15 and 300 seconds (100 casts at 3 seconds) = 447.1305 damage per second.

3.0secの場合damage bonusは85.71%。
1341.3915 damage。
100 cast = 13,4139.15 / 300sec = 447.1305 dps


487.1478 / 447.1305 = 1.0895 – a.k.a 108.95% or an increase of 8.95%.
8.95%のdps増加。

100 casts = 12,1786.95 and 200 seconds (100 casts at 2.0 seconds) = 608.93475 damage per second.
2.0sec castの場合 608.93475 dps
100 casts = 13,4139.15 and 250 seconds (100 casts at 2.5 seconds) = 536.5566 damage per second.
2.5sec castの場合 536.5566 dps

Resulting in a 13.49% damage increase when you reduce your cast time through talents.
Talentでcast timeを短縮すれば13.49% damageが増える。
結論として彼は
So we agree that the changes will buff lower geared (presumably lower level mostly) Shaman, but as the bonus spell damage increases, the damage under the new system will decrease?
Gearの揃っていない人、Lvlが低い人にはdamageは増えるけど、damage bonusが増えるほど、damage量は減る。


If we don't factor in Spell Damage gear, it appears to boost damage output.
If we factor in 1000+ Damage, it drops damage by 5%.
Spell Damage bonusを含めないとdamageは増える。
1000 damage bonusを含めると5%減る。
そこで彼は単純にdamage bonus以外のstatsも
gear構成の重要な要素として考えようと言っています。
2.3の新しいGearはhasteが付いている物が多いようでそれを
対応策として勧めている雰囲気。

what can you be looking for on your items instead of +damage?
I'm thinking +Haste might be a factor here...
