Is it just me or would making fishing a skill be worthwhile, some of the rare fish sell for decent (not terrific though) money, but if there was a skill tree of some sort it would be good to have skills that give abilities to use different bait in the wrong water type, skills that make the fish worth more money to sell, skills that increase chances of finding bait, etc,

Then while the skill levels up, it could also increase the chance of catching rare fish? Thoughts?
