i totally agree with the concept of a high level scripting environment within ue4, the other engine i use has c++ and lua and its wonderful. lua to basically script the gameplay (simple with no compiling), and c++ is there for the more demanding/core elements.
i too find blueprints somewhat cumbersome awkward for anything much more than a trigger, and c++ just too… erm… involved (or a better word) for scripting gameplay.
some scripting layer inbetween would really open it up to some interesting and rapid possibilities.
anyone that thinks is not a good idea cant be seeing it properly.
