Hi i just wanted to write down some of the most important AddOns for the healing in every class
1- Heal Bot: A really important AddOn that lets u make shortcuts in the mouse so u can just click in a player name and heal it or Cure it

2- Grid: A Raid Unitframe That makes u dont have to move the blizzard raid frames to the middle of ur screen very small and very useful
