I'm thinking the Witch Elf will be the most popular class. I heard rumors that with a sorceress with the AOE builds, that they can really wreck large groups of people at once. Even more so, that a group of AOE sorcs can cause havoc. I suppose that's like having a group of Mages in WoW AOE'ing everything.
This is the AOE sorc build I was thinking about
