Yeah, that the point. Carrier has a specific role, it can only carry interceptors. The cruiser has a role, it can carry nuclear weapons. Every ship in Stellaris don't have this role, because cruiser just like battleship can carry regular weapons or torpedoes or interceptors. That why I don't understand why people want to have them to be so different, if the ship type only determinate, how many weapons it would have. Want more hp and weapons for higher price and less mobility? Pick battleship. Faster ship with less price? Pick Cruiser. Because both can carry Interceptors, both can carry torpedoes, both can carry regular weapons. This why I don't understand why people want to build ships with less hp and fewer weapons to be viable in the late game? Why everyone sees every ship type as something totally different, if they are just a simple tier of the same ship, where it would get more hp, more armour, more weapons with every next tier?
