Decimation & Soul Fire

#1 » Post by **testeromir** » 24 Jul 2015 12:05

I have recently noticed that soulfire behaves strangely.
Quartz and standard wow tooltips show different cast times for soulfire when it is under decimation effect, which can be seen on the image below.

So I've been doing some calculations and I concluded that if decimation talent modifies base cast time of soulfire, then cast time should be the one that quartz shows, and if decimation modifies cast time of soulfire atm (cast time which u get after applying Bane talent 5/5 (-2 sec) and haste calculation) it should be like wow standard tooltip says.

So my question is next, is decimation supposed to lower base cast time of soul fire or not?

Offhand I'd say the value shown by Quartz is correct & that the tool-tip for the spell is not being updated by the talent effect, this is a common issue with many spell/buff tool-tips in wotlk.
Even on retail WotLK spell/ability/buff tool-tips were notorious for not being updated when talents modify them & was a bug Blizzard was too lazy to hot-fix till the launch of Cata.

Then again it might indeed be bugged, will need to check into some retail sources to be sure.

So you think that decimation lowers base cast of the soulfire?
Because tooltip gets updated from 2.6something to 1.57.

Cast time reduction is NOT a source of haste. Anything that reduces (or increases) the cast time of a spell (like Bane, Emberstorm, Decimation, Backdraft, and Molten Core) is applied to the base cast time BEFORE haste is taken into account.

Since the above info confirms that Decimation & Bane reduce base cast time we'd have to check if the cast time being shown by your Quartz addon is correct using equation for calculating cast time post haste being applied:

Unbuffed Cast Time post haste being applied:
New Casting Time = (Base Cast Time) / (1 + (Haste Rating / 32.79 / 100))
= (2.4) / (1 + (1736/ 32.79 / 100))
= 1.52 seconds

(The base cast time for Soulfire with Bane and Decimation is 2.4 seconds, as for the haste rating value I took your locks haste from armory)

So yes seems like there is something fishy going on with the Soul Fire cast times, since your image shows a cast time of 1.05 seconds for Soul Fire while under Decimation proc when according to the above calculation it should be 1.52 seconds.
Here is hoping my math is correct lol.

As I can see, atm base cast time on TW is calculated like this then: 6 second is base cast time, with decimation it becomes 3,6 sec. With Bane it becomes 1,6 sec. I have around 52% haste so 1,6 / (1 + 0,52 ) is close to 1,05.
Still I dont know is this implemented like it have been on retail.

Ok I have actually ran some tests, here's one:

1.6 / (1 + 0.2562) = 1.273 sec
This confirms that Testeromir's formula is the one being applied at the moment on TrueWoW. However it doesn't make sense

I mean, why would Decimation's cast time reduction be applied before Bane, which modifies the base cast time?

Well its confirmed then, Decimation cast time reduction is being applied incorrectly on TW.
I wonder if other spells we use have a similar bug.
Just for future reference base cast times post talent reductions for our spells should be as be as follows:

Lol the Demo/Hybrid nerf is going to be real xD
By the way, a bit off topic but I wanted to add that the above Haste calculations have proven that Haste conversions work perfectly after the fix that happened months ago. Some people had doubts [emoji14]

Well before we talk about nerfs to any spec tests will be need to be done with the other spells too, if they are bugged like Soul Fire is ATM then ye, if & when the bug gets fixed some specs will feel the weight of the nerf bat [emoji14].

By the way, if you nerf this please fix Felguard !
Demo will be shit otherwise

So I finally got around to reporting this issue with Decimation to bug tracker, as well as Backdraft.
