Why SharePoint Designer has no design view

There is no design view in SharePoint Designer 2013 only code view is available for you to just insert your code and develop workflow.
If you look back and see what type of IDE SharePoint Designer 2010 had so it was quite easy for people to customize such stuff, user had code view, design view and split view for customization in SharePoint Designer 2010 where as design view and split view have no standing in SharePoint 2013 Microsoft has discarded design view in SPD 2013– this removal including design view and split view affecting people who are editing web parts and master pages in spd 2013.
How you can cope under such circumstances so the solution is- Microsoft says you could use visual studio for such kind of activities means for branding you need to work with VS.

Why SharePoint Designer 2013 does not have Design View:

As you know Microsoft have removed design view from SharePoint Designer 2013 but there is another solution for this problem, Microsoft says – if you want a WYSIWYG(what you see is what you get) editor for branding in SharePoint designer 2013 so you can use expression web and expression design and once done with branding then import that html files into SharePoint 2013 server  using new design manager and further you take it from there.
We have not used data driven control in expression web but you will find data source control in expression web. So people who are feeling that SPD 2013 does not have any design view for data view web part can try expression web where you will find various web parts. Though you can do many things by inserting code in a code view windows in SharePoint Designer 2013 but design view had different features as per power user point of view.

Reasons for Discarding Design view from SPD2013:

Microsoft says- SharePoint Designer 2013 does not have a design view because it’s obsolete technology and has no more support of HTML5 tag and some css tags so it’s better to discard it. So now using sharepoint designer 2013 you can edit UI and change master page but with code, you can do a lot.

Tip: you can design Visio diagram and give life to that diagram by importing it into SharePoint designer 2013 and build business rule using SharePoint Designer 2013 with that diagram.

If you find something new in expression web so please comment and let us know.

updated:
A web designer can use Dreamweaver as  SharePoint WYSIWYG tool. because you can edit your header or navigation there and SharePoint designer can generate .master file against these html versions side by side.
