I interpreted this "boost" as meaning that her magic is stronger when she's transformed. But that doesn't mean she has bigger magic-power reserves too.

And what good is increasing her magic power anyway in situations where she doesn't use it? That she could go hand-to-hand with Azir (or whatever his name was decided on to be) was out of the question from the start and she didn't have any premonitions, nor even seemed to be trying.

In other words staying transformed was just a burden to the team for no better reason than self gradification. And since Carla was one of the few FT mages to stay mostly calm and logical it really grates at me that she of all people would suddenly make such illogical decisions for for the sake of having one more fan-service provider.

Her entire personality changes once she's transformed...
