As a main healer, if you pulled it, you better plan on tanking it or at the very least, hope like the hell the tank gets them off you before you die. I only get a handful of "save your pathetic arse" heals and I'm not wasting them on every pull. The best you'll get is a Eukrasian Diagnosis. If it was an "oops, I got too close", I might save you ('might', meaning that the tank under active attacks *always* gets the first heal). If you Leeroy Jenkins right into every room, that's on you. It's about "resource management", not "griefing".
