KMC Forums - Xenogears: Xenogears Special Option Abilities

As we know Weltall-2 transformed into Xenogears after contact with Zohar and Wave Existence. Before its transformation, Fei had the system-id that allowed him to use Id's power without I'd taking control. With Weltall-2 transforming into Xenogears, the special options for Thor Wave, Flaming Hell and System Id were gone. In this state, Fei became one with Id, or vice versa and if Fei had that unification shouldn't that be beneficial instead of a hinderance. With Fei being One with himself, he should still be able to use Id's abilities and to a higher degree. With that, All three abilities in the special options should still be available along with a few new one's. I wouldn't minded seeing the Xenogears version of Fukei, Chikei, and Suikei or a Super Guided Shot along with a rushing attack similar to Flaming Hell installed into the special options. Why did they take his abilities from the special options out?
