That time Dazzler was flying, you sure she wasn't using solid light blasts from her hands to keep her up in the air? If that's what you are referring to, she'd have to be suicidal to try that in a fight. She had like zero maneuverability and all her concentration was wasted on trying to keep her aloft.
Regarding Dazzler's constructs, how big and how durable are they? Aleta's been doing solid light constructs since forever. She's even cushioned the impact of a star ship to prevent it from crashing using her solid light powers. She's also very maneuverable in flight. I can't see her losing to Dazzler at all unless Allison got a lucky shot off while Aleta was distracted or something.
