Ease of use. It's just another tool in the toolbox. Epic has mentioned how a portion of Fortnite was built using Blueprints. It helped them to prototype features and get the game built quickly. Think about how handy it is to have a diagram, picture, or plan before writing a single line of code. Epic takes sections made using Blueprints and rewrites them in C++ for better performance. After using Blueprints for a bit I can see its merit and why it's useful. Unfortunately, I can't find the source where Epic talked about this. I think it was a GDC talk but I could be wrong. :\
