From my limited experience of Unreal Script it was a pretty rough implementation of a language, it really didn't seem to provide any real benefits.

What I would have liked to see was better support for interactive development. When I was playing with it I still had the edit/save/compile/run loop to see my changes, that's not what I want. I use Common Lisp extensively and appreciate the power of a REPL, it's available in many languages now. This brings me to the next point of providing powerful reflection support so that I can easily explore the state of the application, as well as better debugging tools.

UnrealScript was just not a very good language implementation in my opinion.

So in my opinion removing it and exposing the C++ is a good thing. But not for the same reasons that most are touting, I don't want to code in C++. But now it should be a lot easier to build a reasonable Lisp on top of Unreal Engine 4, which is what I really want.
