Most WYSIWYG stuff I've used (long ago, mind you) was quickly not granular enough to be worthwhile. Very often I'll be working with HTML that is any of these:

- initially hidden

- meant to be rendered as part of a larger whole

- needs to be a specific element, have a specific structure, have a specific ID / class

- contains serverside code / include that renders additional HTML

- is actually a domain template language such as Mustache or Smarty that the tool may not understand

- is greatly changed by CSS (which may itself need to be compiled, such as in the case of LESS or SASS)

WYSIWYG tools usually can't grok the context of cases like that and if you try to use them, they end up taking more time than it would to simply write out the HTML oneself.
