I'm very much of the wait and see mind - I'm uncharacteristically positive about the xpac, for now anyway.
But, I think you do have a point - alarmingly it seems that instead of adding utility to WHM they gone the other route and smashed it out of the other two healers. Which is not really a great way to do it imo.
But we'll see I guess. I'm still going to do 90% of my dungeon runs on WHM, I'm pretty sure.
