But you need to invoke the principle of "we are part of the measurement system and become entangled with it, which in combination with decoherence leads to our experience of "quantum jumps"" which is not that much easier to understand and you still have to introduce the Born rule somehow if you want to predict probabilities. The questions in your comment may be good questions, but the MWI doesn't really answer them either.
