Deep in the Alik'r desert there is a world boss that I have yet had a chance to fight.
Oh I've been there. I've made the mistake of fighting Staada only to not receive an achievement. I've waited for her to summon whatever it is that should be coming through that portal. I've yelled at others to wait.
The longest I've seen a group make it so far was 13 minutes.
I've heard literally everything as far as her trigger. 10 minutes, 10-20 minutes, you have to aggro her first. I've yet to see anything summoned and she seems awfully weak to be the actual boss for that area so I doubt the achievement itself is bugged.
Can we get an official posting on how that boss is supposed to work? Is it bugged? Will she ever summon something? Or does it work perfectly on a 20 minute timer that we're doomed to never reach because someone, will always ruin it, maliciously or otherwise.
And if it is on a long timer, I suggest you take all the designers who thought that was a good idea and lock them alone, in separate rooms with nothing to do for that amount of time and ask them, how they feel about the wait.
