The most important thing is that APIs like Chaos, Niagara and many others become production ready ASAP. Then full updated documents on all APIs that UE4 is made of should become available to the public (for BP,C++,Python). And fixes for known critical and serious bugs should not be delayed forever. And it is time for either Python or a new intermediate programming language to exist because BluePrints are nice for small algorithms but become a huge pain to use for anything really complex (anyway if full updated documents to be able to fully use C++ quickly on all APIs were made available I wouldn’t care about that too much, I would use C++ first) Is that impossible to achieve? I don’t think so. It just depends on what Epic Games really wants to deliver. They have the money to make it happen.
