For those who were wondering if they were missing much choosing Elyos vs. Asmodians, I can tell you that there honestly isn’t too much of a difference beside the color palate and Asmodians being generally angrier than the Elyos. I decided to take my Templar, Sulys, to level 10 to do the Ascension quest just to see the differences. The only storyline difference is as an Elyos you are a Daeva already that has lost his/her memory due to a blow to the head by the bad guy. In the case of the Asmodians you are a warrior who ascends to glory as a Daeva. Same basic quests, areas, and similar cities correspond to questing areas. Some images below from the Asmodian Ascension quest:

The Mau beastmen look pretty cool.

I'm not sure everyone was really happy I became a Daeva.
