Archimonde, Iron Juggernaut, and Pet Health

Good Evening,

Since the submit a bug and in game help are of no use I’ll post here, because I would like to see some effort eventually to fix the game I’ve loved for a long time.

Bugs-
-Archimonde (hellfire citadel) despawns and doesn’t give loot.
-Iron Juggernaut, killing before trolls die leads to gate not opening.
-Pet health (BM hunter) is lower everytime I mount flying, pet despawns, and I land. Farming nodes leads to pet health being depleted.

Please someone at Blizzard take the time to listen to the bug tickets that are being submitted and remediate some of them. Thank you.
