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…
