Blueprints, or node graphs more generally, allow people to encode programmatic logic without needing to learn the syntax of a programming language. If they can read a flow chart, they can implement simple (or not simple) functionality without the perceived technical hurdle of "learning to code." This is important in games because iteration is so critical to success. Delegating high level logic to visual scripting can allow different people to focus on low level concerns like performance, so both problems can (hopefully) be iterated on in parallel.
