May I ask why you think blueprints are horrible and must die?
Personally I like them an awful lot and could not see any reason behind your request.
They simplify so many parts of the development even if you don’t use the scripting part at all (because of the way you can edit all components and just about everything really easily). But even more it allows you to rapid prototype really quickly some idea. Sure it could work fairly quickly with code as well but there will always be a barrier and especially for artists I can not see how a pure code environment would make anything easier.
