I mean yes the final product which is the game itself is sure as hell enjoyable. But the editing process itself and working with the Warcraft 3 editor? haha I don't think so at all, unless you are into some sorta nerd bdsm. That is like enjoying typing feedback and bug reports, that is just plain boring. You only do it for the final product. Yea small part of the editing might be enjoyable but most of it is pain. It takes extreme dedication to focus yourself on a map and work on it every day and get expect no gratification for A year or more even.
