Another question: I've read that a resto shaman is a must have in instances. So I do plan to dual spec 1 shaman dps/heal. Given my rather limited skills, will that be enough or is it wise to dual spec a 2nd shaman for when I'm in deep trouble? Note that I don't want to bring in a 3rd class for a long time (like my dedicated 60 priest healer) because it will get too complicated.
