Peculiar Harmony

A slight extension to my previous topic 'polymath kerbals' : Yes, specialised skills. Instead of just being a 'pilot', a kerbonaut can either be a plane pilot or a rocket pilot and why not both? A pilot has to be trained in both fields to fly our dear SSTO(as mentioned, I have posted this new multiproficiency idea in a different topic) which adds a nice little challenge to SSTOs and not all pilots are qualified to fly out state of the art piece of arts. Scientists can be labrats or field researchers. I don't have any idea for engineers yet. Although I think having too many specialisations would be overwhelming, 2 specialisations for each skill in my opinion would be enough!

Instead of being an expert in just one field, a kerbal can be an engineer, a pilot and a scientist at the same time but they have to be trained to be so. They come with their default degree just like in KSP 1 and they have to be trained specifically for the field. i.e, an engineer has to be trained in the specified way to become a pilot or a scientist and vice versa. An idea: For other kerbals to become a Pilot - Can be left as in KSP 1. Engineer - Assisting in builds Scientist - Collecting experiments and being in the science module that is actively producing science. Added advantages: We will care for our kerbals more as they can not just not be replaced as we've trained them specially and new kerbals not only lack experience but also the ability to do multiple jobs. Less kerbals on a ship can work.
