Actually Yoshida said that the original King Thordan battle included about 70% of the existing mechanics in the EX. But he thought it would be too hard for people to beat so he toned it down ALOT so people doing the main storyline could complete it. This is from that interview btw.

Also, have a strong feeling all of their time definitely went into Diadem and Lord Of Verminion. Considering the size of its section of the patch notes.
