We've completed our first set of Wrath Dailies outlining ways to increase your reputation with the Kalu'ak faction. The three quests that you can do are all available to you when you hit Northrend, and are generally pretty easy to swing through if there's not a lot of other people around.
The best way to complete them all is to begin at one of the starting zones and work your way across Northrend. I usually start off in the Howling Fjord with The Way to His Heart since that's the least heavily farmed, then go Dragonblight for Planning for the Future, and finally end up in the Borean Tundra doing Preparing for the Worst.
The Way to His Heart
In this daily quest you have to mate two squishy sea lions. Have fun, and don't forget that soap you made earlier. And what gets two sea lions to mate better than some yummy gooey raw fish?
