When building complex gameplay systems, how do you decide what stays in Blueprints vs. what goes to C++? Do you follow a specific rule of thumb or decide case by case?

When you’re making a big/complex game system, how do you decide which parts to create using Blueprints and which parts to code in C++? Do you follow a standard rule (like ‘game logic in C++ and UI in Blueprints’), or do you decide based on the situation?
