Did it use to be better?
What You See does not appear to be What You Get at all. I find myself doing much more xml than I'd like to because the editor keeps not wrapping things in paragraph tags and not inserting line breaks, as well as losing the ones I've manually inserted whenever I switch back to "Visual" (i.e. supposedly WYSIWYG) mode.
It's also not very powerful at all, more generally speaking.
Other than that, I think WordPress is pretty cool. I'm not much of fan of the 2015 theme, and I find the stylesheet difficult to make sense of (I'm a css noob), but older themes look better and are easier to change as desired.
