The point I've loved most is microservices work best for large teams. I think this is true for most of the cases. As a rule of thumb in API development, the consumer of the API should be another person. As such, if we think a microservice as if it’s an API, it would be a better practice to seperate the teams developing different microservices. For a team of 4-5 people, it's a rather tough thing to accomplish.
