YES!! I totally agree! Their approach is extremely frustrating!! 
I have been using the original WIX Editor for a couple of YEARS now, and have yet to make my website public. Why? I am embarrassed by the way it appears and functions due to their neglect of making responsive elements (and contrary to what they originally promised.)
In addition, WIX has launched several features that were not fully complete, rigorously tested, nor checked for errors. I accuse them of being “trigger happy” - inclined to shoot before clearly identifying the target.
What I mean by this is… they get too excited about launching a new product before it is ready to be launched. Yet they advertise it as though it’s the greatest thing to use. It’s false advertisement.
Believe it or not, I am routing for WIX to succeed… I really am. But I’ve been disappointed with their integrity and false claims, and here it seems that you are too. That’s a shame.
I am hoping that the WIX team of experts and developers will change their methods for the betterment of ALL their customers - those using WIX Editor AND Editor X.
