You can't just add a skill point to get a better tractor beam. You need to actually find and obtain a better tractor beam. You also need to make sure your ship is capable of using the higher tech tractor beam (power and crew requirements). Since you rely on finding your "skills", your tactics constantly evolve based on what components you find. This is especially true since not all component types are available at all levels. Another interesting thing is that getting a new "skill" is no longer tied to leveling up and can be obtained at any time. A new awesome component might drop during the next fight. And the last nice thing about components as skills is that you can easily remove any component and add a new one any time you want with no penalty. On the flip side though you only have a limited space to install components, although this grows as you gain bigger ships.
