Just killed Koldrak, it took 12 minutes. We were 12, 1 was afk at the beginning.
I assume that the developers were counting on the fact that Koldrak groups would consist of conscientious whales? So - no! If the group only consists of players with low gear, of which half is afk, people are doomed to either be stuck there for half an hour or just leave. Why don't the devs just leave Koldrak alone, as it's getting a lot of problems with every update?
