Weakaura is simple and easy modification from Growl's original design. Includes current top DPS in a Dynamic Group to prioritize when multiple high damage cooldowns are active and player would benefit from 25% haste Power Infusion. Feel free to move items up and down on the list to give classes/specs priority over another among callouts.
To change sounds on-show, select the macro group "Power Infusion Dynamic Priority" -> Actions -> On Show -> Play Sound. Either unselect or change as desired.
To change load rules from current Class Priest, Instance Type non-raid, and Role Healer move to macro group "Power Infusion Dynamic Priority" -> Load ->
Feel free to comment on suggestions or problems. Just a helpful M+ pushing tool that is free networking for my Priest friends!
Enjoy!
