We are aware that the previous update to Runes and Sigils, coupled with the balance updates released this week, created a situation where boon duration has become a more highly-valued resource.
As you can see in the December 11 release notes, we’re moving toward a world where various professions are specialized at offering different boons and not all boons can (or should!) be provided by a single profession.
Toward that end, we wanted to let you know that we’re looking at new attribute combinations for the coming year to offer you better options. You may want to watch for those updates before making significant changes to your gear.
