@Magiseanzz: As a fellow healer, my advice is to just not heal those who give you such trouble. Some people have to learn from actions; if a particular tank I'm with runs off without taking Protect, I assume they don't want my heals either. Better yet, I stand next to them and start desynthing fish. Or repair my gear one piece at a time. I have a cast-Protect-once policy. Even a macro: "Casting Protect now, if you're not in range, too bad so sad <se.10>". And if they're not in range, I'll assume they're not in range for heals either.

They can Leeroy Jenkins all they want, I'll be alive AND have my chicken as well.
