I keep seeing all these threads about healers whining and complaining that they can never find tanks who "understand aggro mechanics" or "can keep threat". That almost every dungeon they enter results in the tank losing threat and them getting killed.

The common denominator in all those situations is the healer.

Let me give you young healers a pro tip- Overhealing generates more threat than your tank can put out. If you heal someone who is already at 100%, you will DIE. Yes, that includes casting Medica or Succor on your party when only 2/4 or 3/8 members actually need it. That overhealing DOES register for the members who don't have any damage.

So remember, healers, that next time you want to yell at the tank for losing aggro to you... it's probably your fault.
