The reasons for discontinuing the daily offers feature:
- A full year record of recipes offered has been collated. The recipes offered are random, at least in terms of the day-of-year pattern.
- The trading post is (currently) saturated with recipes such that they're less than 5g, so you may be better off instead buying about 6 Pact Scout's Mapping Materials from each vendor instead and wait for the Frostgorge Sound map reward week.
- Collecting the recipe data cost me about 18 silver and 10 minutes per day, and the two reasons above seal the decision.
I hope that you have enjoyed previewing the recipes and have acquired every account bound ones that you had yearned for.
