I had a bizarre Minotaur Artificer Ghost of the Past that was a lot of fun. He didn't seem that much more complex in play than other leaders, but I suppose I have a high tolerance...
I found the Artificer's class features to be rather hard to remember. You were basically giving other people buffs that they had to remember to activate sometime during the adventuring day. My experience was, it just never happened. Wasn't a successful design really. There were some other things I just didn't like that much.
Shaman are great, but just fiddly as hell to play. Great class if you're really into chess-like combat! Still hard to play and lots to remember.
