We've made several adjustments to address DPS balance within the healer role. To ensure all sages felt the benefits of these changes, regardless of playstyle, we chose to increase the potency of Phlegma III. Because its unique recast timer does not hinder the use of other actions, we believe this change will result in improved DPS.
So, I'm happy they gave a reasoning and buffed Sage's Phlegma, but since they mentioned several adjustments to the DPS balance within the healer role instead of just one, where are the other adjustments? I only see Phlegma III in the 6.28 Patch notes. Did they forget to include the rest of the healer role adjustments?
