The issue Druids were having with their Clearcasting proc from the Courageous Primal Diamond being overwritten by their Omen of Clarity proc also named Clearcasting has been corrected.
Courageous Primal Diamond should no longer have its Clearcasting effect get overwritten incorrectly, and the Clearcasting effect should no longer activate if the character is not in combat.
The unfortunate part about this hotfix is that it also prevents healers from testing out weak auras, rotations etc while not in combat. If you are looking for a non-annoying place to test in combat, try the Pools of Purity area on top, the small mobs there don’t hit hard with very little pushback, but they won’t insta-die like critters when they attack you.
