Remove Kalu'Ak NPC from Dalaran on event days.
A person's first and initial reaction when doing a quest isn't and most certainly shouldn't be to check if the quest is bugged in the website's bugtracker and while with some quests it becomes OBVIOUS within the first few minutes, quests with a low drop rate (such as the Kalu'Ak hunt for the shark) can take 200's of attempts before a person can say for sure that the quest is bugged and that they are not just having a bad luck with a 0.05% die roll.. My suggestion is to remove such NPC's from the game so people wouldn't even go for the quests to begin with. I just wasted an hour of my time before I got the 200 fishes down (200x0,5 = 100% chance to get a shark within 200 attempts) and this time quite frankly could've been spent on something far more productive. Very disappointed indeed...
