I've added these notes to the OP in this thread, as we are now testing:
Mastery: Harmony healing bonus reduced by 9%.
- 午时已到 (Azerite Trait) damage reduced by 34%.
Developers' note: Restoration Druid has an overall package of healing, damage, and utility that is very hard to compete with in solo-healed content. Two things that stand out in particular are the efficiency of focused healing on a single target with high Mastery, and the ease of contributing DPS with very little GCD usage on 阳炎术.
The damage debuff applied by your Guardian's Azerite Spikes has been reduced to 3% increased damage (was 5%).
Please note, the 午时已到
reduction we're testing only applies to the Restoration spec.
