You can assume that if Adobe Muse CC can't do all of it, then the entire site needs to be redone with everything hand-coded. That's generally not the case, but it would depend on the specific needs of the site. Today, Adobe Muse CC is a great tool for creating websites with high-quality visual design and no integration with a content management system (CMS). That is likely to change as we add CMS integration and explore enabling creation of websites for mobile devices and tablets. Just like in the early days of desktop publishing when Adobe PageMaker® software could create only a small subset of all the possible typeset publications in the world, Adobe Muse today can create only a subset of all the possible websites. However, for websites in that subset, it's a far more efficient tool than hand-coding.
