From the World of Warcraft blog:
While we aren’t always able to provide advance warning when an ability changes, there’s still some time before this change goes into effect, and we wanted to offer affected players a chance to plan their strategies appropriately in the meantime.
The following changes are currently planned for retuning the Druid talent, Heart of the Wild:
The spell damage bonus that Heart of the Wild provides to Feral and Guardian Druids will soon be reduced from +500% to +320%.The agility bonus that Heart of the Wild provides to Balance, Restoration, and Guardian Druids in Cat Form will soon be changed to +110%. It was previously +50% for Guardian Druids, and +200% for Balance and Restoration Druids.
Currently, the change is expected to go into effect during next Tuesday’s maintenance.
Goodbye, Moonkat, it was fun while it lasted!
