Forgive me if this has already been addressed but since I don't see anything in the upcoming patch notes under Warlock Bugs, I presume people are not aware of this.
It seems there has been cases when whilst using Soul Fire, I don't gain the Improved Soul Fire buff. At first I thought maybe I had clipped a spell or two, but after noticing it several times, I came to the conclusion it definitely wasn't poor Soul Fire management on my own behalf.
This occurs when someone uses Time Warp, or Bloodlust/Heroism. I lose my Improved Soul Fire buff, and it cannot be reapplied. It infact creates a 40second internal cooldown for Improved Soul Fire I believe, since I have tried cancelling the effect of Time Warp/Bloodlust/Heroism and using Soul Fire, still no buff gain until ' around the time where Time Warp/Bloodlust/Heroism ' would drop.
My thread title is a question as I am not sure whether this is a bug, or whether its intended, part of me believes its intended due to the absurd amounts of spell casting we could reach during Time Warp/Bloodlust/Heroism if we could have Improved Soul Fire up during it, however part of me believes its a bug due to the fact there is no mention of it, there's no mention of Time warp/Bloodlust/Heroism cancelling the effect or the effect not being procable during Time Warp/Bloodlust/Heroism and from what I have read regarding EJ threads/guides/etc on Warlocks theres no mention of ISF not maintaining ISF during Bloodlust which would be a key factor of the rotation interms of maximizing DPS.
If this is also a bug then I hope it doesn't have an ' after effect ' on the ISF change 'causing the 8% damage gain to not be procable during Time Warp/Bloodlust/Heroism in the next patch.
Posted this on Official Forums too, wanted MMO-Champions opinions also however since Official Forums never seem to reply to any of my threads.
