3 healers, 1 main

[Deleted]

In MoP i decided to lvl my shaman first to 90, now's the druid's turn, and then follows the paladin.
I plan to play every one of those three will play as a healer in pvp at 90. Unless things change of course.

I hate and love some things about each class, I know their weaknesses and strengths pretty well.
But I have no actual 90 experience with neither my druid nor paladin and my shaman's is limited.

What I want to know is which one out of those three do you think is in a better place than the others.
And by this I do not mean which is the most strong/overpowered.
I mean which one out of those three has the ability to play decent well at a bigger variety of comps in arena.
So, which one is the "most viable"?

Im liking shaman but in the right comp each will do very good. bgs I find I heal more with my druid.
