World of Warcraft

I've been really into the wow lore lately, I know some people aren't a fan but I really quite like the systems they've made.

I think it's really interesting that we've seen an equivilant of the titans for the force of death as well. Do people think the Naaru are the equivalent for light, or is there a force above the naaru even more closely tied to the force of light?

If the next expansion focused on one of the forces we've not seen, what would people most like to see? We don't know much about Life apart from what the titans and azeroth beings have done. While the legion is gone, there may very well be still the titan equivilant for disorder, I could see an expansion set around going into the twisting nether. Of course the most likely is focusing on the void and finding out more about the forces behind the old Gods.
