UW glitch/quest issue

I am not sure if i just dont understand the quest properly, but in the UW quest where u have to protect the king, from the 3 waves of 6 dryders i had a weird problem. I took a OF build, and managed to tank the dryders slowly killing with Sliver armor, first 6 appreared and i killed 1, then the next 6 appeared and i killed 3 more. When the third group appeared we all lost on account of "displeasing grenth"? None of em left, i adh all of them aggroed. I dont see why???

Pretty unlikely that this happened, but is it possible you didn't clear the area well enough and a patrol ran into the ice king?

Yea it sounds like there wasn't enough control of the area. I imagine that the ice king got iced.

On another note. If you feel like you've found a glitch or a bug, it's probally better to post it over in the bug section.
