Use the engine as it is like Sivan , SuperKu did, and some other people working on Battle For Forgol for example.
It's to you to use actual 3DGS good capabilities

New WED won't make your game better , if it's already bad looking in actual WED

Yes you'll have perhaaps better workflow, but the game depends lot more on what you can do , not only the engine editors

So some people should stop waiting and go "hard work".
