yeah mast+crit is what you'll be using for both in most raid fights
haste+mast gets a lot better for resto in dungeons where you won't be going oom often and get a lot less benefit from crit (Because a lot of your dungeon healing is from tidal waves+healing surge)
haste and crit also get better for ele in situations where you use earthquake (it's a very noticeable dps gain on some raid bosses or to swap the 2 ele sets in dungeons)
