Hi,
Not sure for others but my guess is that most of us are just not using a visual designer. If you meant MVC or Web Pages you can't anyway as you are really writing code that renders markup when it runs.
With a bit of experience using markup is much more efficient than a visual designer (expect maybe for pure design work). I'm not sure it's really the designer quality. IMO creating dynamic pages is not well suited to WYSIWYG by design.
