But it can do nothing well. In a group a Shaman will always be wanted but often it can be a rather boring existence. Of course this will depend on you, some people will enjoy this. If that is your priority you will get a lot out of the Shaman. Well kiting is a touchy subject.
Some people hate it, others love it.
Some people will go from level 9 to 50 on their own kiting. It can work well. A simple drill. Just use DoTs, count to 42 or 120 depending whether it is disease of poison and re-apply. SoW lasts ages.
