I spent the first 2 hours of Mists trying for realm first fishing but unfortunately someone else beat me too it by 2 points. Although a bit disappointed I carried on with my plan and started the farming, did some pet battles and kicked off cooking. I then noticed that realm first cooking had not been got; strange!
Originally I did plan to do cooking but as it was so easy I thought there would be too much competition; it should only take 30 minutes. So with the fish I caught and Zalid's help I went for it and to my surprise after 3.5 hours from release I got realm first for Cooking!!!
Many thanks to Zalid as I would not have been able to do it without his help!
