Well, Anet had three years to come up with new ideas between Zhaitan's encounter and the two Mordremoth encounters, and obviously the themes of the fights are different: in Zhaitans, you're basically in a glorified gunship battle against a dracolich. The fight against the mouth of Mordremoth is one long infantry campaign against a snake head, and the true final fight against Mordremoth involves beaming into his mind ala The Matrix/Inception and overcoming your personal demons and old regrets, and fighting against Mordy's pride.
Additionally, what would you like to see for the boss battles against the other Elder Dragons (assuming they continue to be expansion final bosses)?
