This comment is written from the perspective of a Horde player:
This quest and other dailies in Domination Point, Temple of the White Tiger (Temple of the White Tiger seems to be working again) and Nuzio's Temple, plus the fisherman in Pandaria that gives you the clue where to go to get the catch of the day have ALL been broken for quite some time. The closest I can figure is that everything went out around the 6.02 upgrade. I have been leaving bug reports over and over. I have opened ticket after ticket, only to get some stupid reply like "You need to delete ALL of your add-ons." (I actually tried that nonsense and it made no difference.) What happens is the targets of the dailies don't appear on the same day that the actual daily quests are given out. So you get a quest to shoot down helicopters, but, no helicopters. You get a quest to destroy supply drops, but no supply drops. You go to where the fisherman says, but no pools of fish. I must have opened 50 tickets on this issue in the last 6 months and Blizzard has completely ignored me. Oh yeah, once a GM told me that everyone was soooooooo busy programming that it was taking "days" for them to be able to respond to bugs. (Now I see they were programming a new "Coins" feature so that Blizzard can rake in even more money off of everyone!) But I figure that when you are already raking in MILLIONS OF DOLLARS A MONTH, you should be able to afford to hire enough workers to keep the game up and running properly. Hell, they cannot even respond to a GM ticket on the same day that it is submitted any more. I have been playing WOW for over 10 years, since it first came out. Customer service is nothing like it used to be, even though they now have more paid players. Ok, sorry everyone for the rant. But now on to what we CAN do...
Note:
There IS a WORKAROUND to this dilemma, although it is not the best. In Domination Point some of the dailies can be hunted down in a slightly different area than where you expect to find them. When you get the Flash! AAAAHHHH! quest gyrocopters are supposed to fly over the Domination Point fortress, but they usually won't appear there. However, you can fly out to sea to the Alliance airship. Head southerly from the fort towards the Alliance ships in the ocean. Above the ships you will see an airship flying. You will find the Gyrocopters flying around underneath that airship. If you haven't done it yet, create a macro that will make knocking these gyrocopters out of the sky a snap:
#showtooltip
/target Skyfire Gyrocopter X2
/use The Bilgewater Molotov
Just create the above macro and put it on a hotkey. Then fly around under the airship spamming the hotkey and when you get close enough to one the macro will do all the work. When you get the quest Death on Two Legs to kill Alliance NPC's on the beach you can instead run around the grassy areas just off the beach and around the fortress and spam TARGET NEAREST ENEMY (Have this on a hotkey. I keep it on a permanent hotkey because I find it useful to spam to target enemies all the time.) and cloaked SI:7 Saboteur NPC's will appear that you can now kill to complete the quest. What you have to do to complete the other dailies in order to get the rep you need, is that you have to keep these daily quests active in your quest log once you get them. And then when you visit each site look to see if they are active that day. Eventually the quest objects WILL show up and you can complete the quests. The downside to this workaround, of course, is that you have to clog up your already full quest log, and you have to do a lot of unnecessary traveling, which sucks. But, that is what Blizzard has left us with.
Also, now that we have the ability to travel cross-realm, you can download the addon Cross Realm Assist and use it to see if you can find these daily quests active on other realms. Just make sure you adjust your group search to exclude Raid groups, as you cannot get quest credit wile in a Raid group.
The whole point of doing these dailies is to raise our reputation with these factions in Pandaria. One thing we can do to increase the reputation gains is to do the daily Work Order quests for the affected factions in Halfhill where you plant the herbs that these factions need. You will find these dailies under the blue exclamation point on the post next to the steps up to your hovel at the fields where you plant your crops in Halfhill.
P.S. For the last month I have been logging what dailies spawn and when they spawn. Hopefully I will eventually figure out a pattern and if I do I will post and maybe we can figure out a better way to work around Blizzard's lack of concern to fix their own game errors. After tracking these broken dailies for over 2 months I have come to the conclusion that the dailies show up randomly and there is just no way to predict what daily will show up when. In the meantime, EVERYONE needs to keep submitting the game bugs to Blizzard!
