Compared to Necro, how well can Shamans solo?

I've often heard in class discussions, when folks are asking what the best class would be for someone that needs to solo a lot, needs to make frequent AFKs and such. And I hear necro and monk being mentioned most of the time due to their FD.

In other discussions I've heard of Shamans being one of the absolute best solo classes in the game as well, right up there with Enchanters, especially when they get Torpor.

I ask since I'm in a bind, trying to figure out what I want to play. I currently have decently geared characters on both Blue and Green; blue, a 31 mage, and green a 12 shaman. I want to play something evil because that's simply the way to go in this game and I'm debating between sticking it out with the Shaman, or whether someone like me should be playing a Necromancer instead, who does tend to solo a lot, does need to frequently AFK and wants the power to solo as much as he can.
