The quest provides a flying machine that the player should ride and use its abilities to fulfill the objectives. The machine is provided, but it doesn't autofly along predetermined route (it can be piloted directly by the player), and its abilities don't do any damage to the quest objectives. The first ability (Full Autofire) can be used, but doesn't really do anything - it looks like it's firing, but it is just a visual effect that can't be targeted onto mobs in any way to deal damage. The second ability (Torpedo Rocket) can't even be used.

While it's possible to kill the required 60 Garrosh'ar Horde and 8 Garrosh'ar Shredders manually without the flying machine (slow, painful and annoying as it is), the other 2 objectives - destroying the 2 ships - can't be completed (I was kinda hoping there would be an object on the ships that I could click to destroy them, or that they would at least auto-complete after I killed the required number of enemies, but that didn't happen).

Also, phasing for that initial area is a mess - the sha creatures shouldn't be present in the area before player completes the first 2 or 3 quests dealing with the Garrosh'ar Horde. That said, conditional quest unlocking/chaining and zone phasing was pretty much non-existent even in other zones I've been to so far, and while annoying, it doesn't prevent progression, so…

note: the chance to trigger effect 1 is 7% in Legion instead of 5% displayed in 1st wowhead link - this is confirmed by changelog on wowhead and attached screenshot from Wowaddicts Legion server and client

I've only tested effects 1 and 2, which apply to Guardian spec druid that I play. Effect 1 wrongly consumes buff granted by effect 2 (2nd link) in the same talent activation instance, so whenever the talent is triggered, it automatically casts the "improved" Moonfire and grants 8 rage instead of casting basic Moonfire and granting a buff that would apply to the next Moonfire the player casts. I'm not sure what should happen if the talent triggers again before the buff from previous activation is consumed by the player, but 1 comment in 1st link suggests it should consume the old instance of the buff (the automatic Moonfire would be improved in this case) and apply a new instance of the buff which would be again available for the player to use as they see fit. This would make sense, but I couldn't confirm if this is how it was actually implemented on retail.

I've tried porting out and back in. I've tried attacking and fighting for quite a while both of the available abominations - 1 can be bypassed, the other one needs to be cleared in order to proceed deeper into the dungeon. I've tried killing other mobs (the 2nd pack of "vikings") in between the abomination attempts to confirm the bots were still working, and they worked fine on those, but still not on the abominations.

I was doing the dungeon as a tank - guardian druid. I haven't tried doing it as other specs and I also haven't tried other dungeons yet.

Not sure what rules currently control the bots, but at the very least the bots should attack anything the player is in combat with, preferably player's target if it exists, and the healer bot should definitely heal the player if player is taking damage (my healer bot would have let me as a tank die to those abominations if I were not able to heal myself until I gave up and ported out of dungeon to save my life, although it healed me ok on the other mob packs - skeletons and vikings).

This is the best resource/description I could find on the topic of player XP from herb gathering and mining so far, but more research will likely be needed in order to get the system working in a Blizzlike fashion (most notably it'll be necessary to find and implement correct levels for each herb and ore node and items they can yield):

I've fought a lvl 5 frog with my lvl 5 raven. My team had 3 pets on it, all lvl 5, but only the raven participated, so the other 2 pets shouldn't be getting any XP in this case (and they indeed didn't get any XP, so the issue isn't caused by XP being split). Defeating the frog awarded my raven 23 XP. This is way too little - based on the formula on the provided website, it should have gained (5 + 9) * (5 - 5 + 5) * 1 = 14 * 5 = 70 XP. Of course, in a more complex battle situation the formula alone isn't enough to calculate XP for each pet correctly, so please refer to the provided website (and possibly other sources) for more detailed info on the XP calculation in specific scenarios.

When I defeated Julia Stevens in a pet battle for this quest, she disappeared instead of staying where she was and letting me talk to her to hand in the completed quest. This shouldn't happen.

Here are some examples of pets from items that I've tried to get so far:
- https://www.wowhead.com/item=8485/cat-carrier-bombay - https://www.wowhead.com/item=8501/hawk-owl - https://www.wowhead.com/item=8487/cat-carrier-orange-tabby - this one is interesting because this pet can also be obtained by "learning it" from various beginner pet trainers like a spell, and in that case it is actually possible to add another copy of it to the Journal, so the whole issue seems to be more likely related to the processing of the items that "teach" pets, rather than to concrete pets themselves
