If you have been lucky enough to finish gathering your 20 secrets and obtain a Courageous Primal Diamond (click here for the full rundown on the Courageous Primal Diamond with ntoes for each healer class) there is a new addon that shows exactly how much mana you saved using the new legendary meta gem.
The addon is called LMGEffective, which will track your mana savings while in combat, then print out the total mana saved after combat is exited. It is currently on CurseForge only, but I imagine it will eventually be added to Curse.com
Download LMGEffective here.
