As a healer, I personally LOVE it when a tank wants to do big pulls. The current dungeons, as designed, offer only an illusion of difficulty. Larger pulls just make things more exciting. I have to be on the ball, as one mistake could mean everyone's death. I love it!

Standard slow pulls? I'll just let Eos heal you while I run in circles around the mob and Miasma II. Maybe even let out a bad pun or two.

If you think about it, its rather sad. My pet can quite effectively heal most dungeons on its own (apart from boss encounters) when playing them as designed. We need harder PF dungeons :-/
