Yeah but Time Compression takes time to pull off, I mean Squall's party beat her before the spell was complete, not to mention she apparently needs the power of another Sorceress of comparative power to cast it, meaning its not something she can do by herself. I felt the only comparative Villain is Cloud of Darkness herself, who is literally a physical manifestation of the Void itself. Fire with Fire and both villain required a Deus Ex Machina to actually beat.
