My problem is that I don't find 2 of those quests.
First quest Preparing for the Worst, I find it, but the others The Way to His Heart.. and Planning for the Future, I can't find. I do something wrong or those 2 are not present?
I had two of them (preparing and planning) through questing around kalu'ak places. But that's few months ago as things might be broken from time to time. Had you tried enabled low level quests tracker? Kalu'ak quests daily will not visible to you if you are 80.
I've done them all many times. So if it's broke, then this is something new.
You're aware the three quests are in very different locations along the Northrend southern coast I take it? There are three Kal'uak bases and one quest at each of them.
