It's a Fel Reaver, But with Heart quest - too many adds

[Notmittz]

Description: This quest appears to be spawning too many adds and too quickly. They don't stop spawning after the 40% threshold on the main fel reaver either and just continue to spawn. They also don't despawn when the fel reaver is killed.

Current behaviour: Adds keep coming, non stop, and will still fight after the fel reaver is dead.

Expected behaviour: Mobs spawning slowly, one at a time (fight description by warlock) - https://www.wowhead.com/quest=10309/its-a-fel-reaver-but-with-heart#comments:id=136443

Mobs stop spawning at 40%, from a paladin tank - https://www.wowhead.com/quest=10309/its-a-fel-reaver-but-with-heart#comments:id=148329

Mobs should despawn as soon as the reaver dies, multiple comments - https://www.wowhead.com/quest=10309/its-a-fel-reaver-but-with-heart#comments:id=27794:reply=288458

I found a long video of this fight, which details the mobs spawning.

https://www.youtube.com/watch?v=QzZM10omJxc

Fight starts and one (1) add is spawned [timestamp around 0:43] 25 seconds later, another one (1) add is spawned 20 seconds later, another one (1) add is spawned 25 seconds later, another one (1) add is spawned 15 seconds later, two (2) adds are spawned [timestamp 2:06] 20 seconds later, two (2) adds are spawned [2:25] 15 seconds later, three (3) adds are spawned [2:45] 15 seconds later, three (3) adds are spawned [3:05] 20 seconds later, three (3) adds are spawned [3:25] 20 seconds later, three (3) adds are spawned [3:45] 20 seconds later, three (3) adds are spawned [4:05] 20 seconds later, three (3) adds are spawned [4:25] 20 seconds later, three (3) adds are spawned [4:45] 20 seconds later, three (3) adds are spawned [5:05] 20 seconds later, three (3) adds are spawned [5:25] No more adds spawn after this point, but they stick around the fel reaver for a few additional minutes trying to figure out what to do.

Additionally, the mobs seem to spawn pretty far off in the distance and come running in on the video. I'll have to double check in the morning, but I believe the mob placement for where they spawn on Netherwing is near the fel reaver.

The add spawns vary I don't know if its based off how many adds are alive or the HP of Fel reaver but I can say for sure those not all remaining adds will despawn. At most 3 to 4 adds would despawn once Fel reaver is dead, think its just random. Tell me what you guys think of the samples. Main issue of course is some of the adds wont despawn and if there is 5 or more, only 3-4 will despawn.
