Dumbest Nerf by Blizzard

Guardian is overall in a good space, but Mastery scaling has been a bit out of control while Haste has been underwhelming. The main defensive value of Haste for Guardian Druids is to proc more Ironfurs and Frenzied Regenerations - something we want to bring more into focus.

Last night we decreased the health and healing received from Nature's Guardian to 4% (from 8%) and adjusted the mastery amount accordingly, and, to compensate for this, we've increased the amount of armor granted by Ironfur up to 100% (from 75%). You should see more of an impact from haste affecting Ironfur now, and stacking Mastery will be a less effective tactic going forward.

Guardian

• Nature’s Guardian now increases health and healing received by 4% (was 8%). The Mastery amount has also been reduced accordingly.
• Ironfur now increases Armor by 100% (was 75%).

Edit: The hotfix notes have been updated with these changes.

Apologies for the delay here and thanks for all of your feedback - we've been working to confirm that this change was not intended. The Attack Power change on the Guardian Druid Mastery is, indeed, a bug, and will be corrected in the near future.

I'll update this thread once we have more details related to this fix.
