Doesn't seem to me, as it's intended but on Will of the Emperor, it's possible to break the pipes, and fill the room with gas, increasing your melee dmg by 50% while taking some healable dmg over time.
And this is possible on LFR AND Normal, it ticks for the same dmg it ticks for, on heroic.
This'll be great for doing that extra dps, if you're going for a high rank on WoL.
This "mode" Only activates the gas, it does not spawn sparks upon the death of a mob.
I did not kill it in a LFR Group, with this mode activated, so i don't know if you'll still be getting LFR gear, or if it might bug to give you something else.
