Not sure if this has been said but I will give my experience soloing from 1-50 pre kunark and 1-60 in kunark, one barbarian one ogre.

Shaman can solo but isnt very good at it until they really unlock what it means to be a shaman, around 29. This is when you are getting powerful dots and have a pet and a slow that all works well. Its when you get canni and regen when you start being able to solo well.

Solo leveling from 1-29 is not easy at all and if your doing it with no gear its even harder. You will have a low mana pool and alot of the time it wont be worth it to spend mana on a slow that is only 15% when you can just nuke it down or something like that.

Necros and shamans get the same posion and disease spells leveling. The difference is that the necro gets the better posion one and the shaman gets the better disease one when both classes are at the same level. I would say thats what gives the necro the real edge on dots, posion is faster and you can do more damage quicker with it. Also necros have their magic based dots too which shamans dont get.

So Shaman before 29 I would say would level as effectively as a ranger or shadowknight or paladin where they can kind of heal up vs how much dmg they put out solo. But once you get those key spells you are in the category with wizards druid and necros.
