To allow for any kind of font size adjustments it would need to be a pixel based scaling which will affect quality, otherwise SE would have to proof read every dialogue in the entire game to make sure nothing is being cut off for various sizes. Huge headache.
Well, if that's the issue with it, why not let us enlarge the bubbles themselves as we do menus in the HUD?
