That's like saying Nashandra is optional, since you don't actually have to finish the game at all or even buy it.

If you buy the DLC, Elana is not optional to finish the DLC's main story. If you don't buy the DLC, she's still not optional, because at that point you don't even have the ability to fight her at all.
