I haven't seen this issue, I've only actively taken Halaa once though during the level push, where there were not many people in Nagrand yet. But when I go there now, I often see it in either Horde or Alliance hands (though mostly Alliance, PvE server and all).
On Frostmourne 75% of the time Halaa is alliance controlled with 2/15 guards left but no where to be found. I asked a Gm to check if they were purely bugged,invincible,under the world and respawn/despawn etc but they refused and an hour later was still bugged.
Damn guard's in Botanica still bugged too
Money is not happiness. Yachts are not happiness. Hot women are not Happiness.
Being stinking rich on a yacht with hot women sure as hell is though.
Not sure what the current status is, but I spent a few days questing in Nagrand last week and it was almost always alliance controlled with 1/15 guards remaining. I think horde could only take it when the server reset or a GM manually did something.
Medivh is having this problem as well. The horde cannot take Halaa at all.
It's obviously a shame. I had a ton of fun on the beta servers with Halaa; incidentally, even if it were working properly, the alliance:horde ratio is so crazy that the horde wouldn't be able to take it anyway.
I think it was mentioned in the "Defending Halaa" thread, but is this the same problem that happened on Beta? If so, 5ish mages could usually find the bugged guard under the world somewhere and AE him to death. Well, so General Chat claimed, I'm no mage.
Also, the guards have something around 1.1 million hps (the fire ticks of 1% are like 11k) so even if you could find them, itd take forever to actually kill them.
But yea, on Deathwing its the same deal where the allys usually have 1/15 left for hours, and eventually GMs do come and fix it. Then 20 min after the horde caps, the allys have it back and the whole cycle repeats.
Only seems to happen to the alliance here though....imba imba!
