Better hero skill system

The system that is currently worst is probably the heroes and their skill trees. They all feel the same. The only decision for each hero is should I take a fleet or planet skill. So basically after first deciding if you want a pilot or governor the rest of leveling already feels decided. Their ships are a bit boring too. Would be nice to unlock flagships. But what I would like the most now is a rework of the heroes skills so they would feel more unique. Not sure what should be done thou.

Perhaps should the heroes be divide into two groups. Make them Pilots or governors with their own sub groups. So after first deciding what kind of hero you need the rest of the skill picking becommes actual choises.  Perhaps rework the current skill system into three skill trees where some choices might lock out others, so that your pilots/governors can´t be experts on everything and each sub group feel more special. I do like the idea to keep one of the threes dependent on the race.
