Blueprints are a toy. Which serious Unity dev would use UE4 without C#/F# or UnrealScript!?

Blueprints nodes are more of a toy than anything text based could offer.Doing prototyping first with BP, and then moving to C++, who the heck would do such a thing? Only if more performance is needed. Because otherwise this would be only extra work to make up for a graph’s short comings. A Unity dev wouldn’t have to do that.

You are missing the something:
BP is an addition, not a requirement.
