1. Is FW CS6 still positioned as a prototyping application? I'm not referring to making individual graphics, I'm referring to being able to make full pages with interactive features.
2. If so, what is the harm in using it to develop full pages? Is it just that the code is not written as efficiently as if it were done by a programmer?
Fireworks is still a graphics and prototyping application. If you would prefer using a WYSIWYG editor, give Adobe Muse a try.
