F&B hotfix

Grimoire of Sacrifice should no longer incorrectly reduce spell damage while Fire and Brimstone is also active

How severe was this problem? I don't think I noticed.

I'm not even sure what's going on here.  GoSac doesn't buff FnB spells, so how it was reducing them is beyond me and Blizz' coding.  Perhaps with FnB, the buffs to Chaos Bolt from GoSac weren't being applied?  Shouldn't have been an issue...regardless of what the issue was, it's gone now.

Not huge but significant enough, I think the difference was 2.25% based on some theorycrafting done by one person.  

 

Discussion on it is here: http://www.mmo-champion.com/threads/1271984-5-4-Brusalk-s-Destruction-Warlock-guide?p=22620219&viewfull=1#post22620219

 

The basics of my understanding was that an artificial .85 modifier was being applied after the F&B reduction modifier, to remove the 15% sac bonus, which was causing it to lose a bit more than 15%

 

From my tests, it looks as if FNB Incinerate while buffed with Sac are doing this damage: 100*(1+X)*1.15*FNB*.85. This .85 I think is to correct for this 15% increase to normal incinerate. Possibly making the 15% intentional and completely unannounced as far as I know. If you want to test this yourself cast lots of Sac FNB Incinerates, and compare the average value with 100*(1+X)*1.15*FNB, which is just the tooltip you see for incinerate right now times the FNB coefficient. So because (1.15*.85) = .97750, Sac FNB is getting hit by a 2.25% penalty because of this .85 correction factor for the 15% incinerate buff.

So, negligible, but still there.  Oh well, it's fixed.  Good find.
