In our guild we have the mentality among healers, that our job is not a) to top meters b) to keep everyone topped(if it's not needed), but to keep everyone's health above 0. We don't care what HPS looks like after the boss dies. On the other hand, we are just 10/13 HC being quite casual raiding guild with not that much raiding hours.
But I'm not arguing with you (or anyone to that matter). Just trying to calm things down a bit. We'll see what happens, I'm quite sure things will change many times.
PS. I'm talking purely form the PvE point of view. I have no interest towards PvP.
