The standard response to "if you don't like it, don't use it" should be "yes, but also why aren't you playing the map editor?"
Because I wouldn't enjoy that experience, so I dont do it. In other words... I don't like it, so I don't use it. This isn't the gotcha you seem to think it is.
That's a good one, but, some people definitely are playing the map editor. With planning the builds taking way more time and effort than actually putting them down.
