Thats like saying people should have no concern for other people and just worry about themselves. Not a good way to be a good person im sure you agree.
But to answer your question, which i kinda just did on another thread. Most of us are healers first and take a more global view on healing not just our local fish pond. We understand that SS is toxic to other healers ands their enjoyment.
As i said a minute ago, a lot of Disc doesnt like SS. not the class itself. So we would like SS gone but buffs in other areas.
Last xpac glimmer made hpallies op by a long way, and when glimmer got nerfed, if you went to the hpally forums you saw threads where they understood why they got nerfed and while no one generally likes being nerfed, they understood it and were ok with it.
Holly priests can answer for themselves but i imagine a lot of them are frustrated being passed over for disc and want a chance to shine
