A few tricks to add:
  • Use your defensive CD(like Rampart or Sentinel), just before pulling. Taking less damage in the initial pull = less healing needed = less aggro for the healer.
  • Don't use Convalecence unless you are certain the healer is low on the aggro list. The extre healing recieved = more aggro building for the healer.
  • (this one I'm not 100% sure about) On boss, where adds are no problem, use your provoke inbetween. Using it should increase aggro building for the abilities used right after.
