[WARLOCK][DIABOLIST] Infernal Machine don't seem to work

[Mlklock]

Game Version:

11.0.5 live

Description:

Infernal Machine don't seems to reduce the duration of Ritual of Ruin by an additional 1 second

Details:

Infernal Machine should add an +1s of time reduction to Ritual of Ruin reduction while Infernal/Tyrant is active, meaning a 3 shard Hand of Guldan would reduce the duration by 4s, or a Chaos Bolt should reduce the duration by 3s but this don't seems to happen.

At 00:29 the effect is at 10s, HOG is being cast
At 00:30 HOG finishes cast, the effect is at 6s , meaning The Hand of Guldan only reduced the duration by 3s and not 4s.

Reproducible:

Yes

Howto:

Cast a Tyrant and start casting Hands of guldan, notice the duration reduction only equals to the amount of shard spent, this can also be crossreferenced with warcraftlogs.

An Update towards this bug report.

At 11.0.7 Live i retested this.

Found out that A: This talent does work with Chaos Bolt and Shadowburn but, B: It does not seem to work with Hand of Guldan, Call Dreadstalkers or Summon Vilefiend even tough they deal damage.

Its possible that this happens due to the Soul-shard consuming spells for Hand of Guldan https://www.wowhead.com/spell=105174/hand-of-guldan isn't actually the damage component of the spell, the same can be said about Call Dreadstalkers and Summon Vilefiend or Grimoire Felguard.
