My last run I did with a shaman and put everything I could into lightning damage. It needed a 2 handed weapon so I basically just wandered up to bosses and thumped on them until they died in showers of sparks, while the AoE from the lightning arcs killed everything else around me. Plus I had a summon or two to redirect some enemy attention.

Thanks for pointing that out! I was looking for an original source, but the articles Wikipedia uses as sources are from a defunct journaling site. However, you can see at least one of the original articles through the wayback machine.
