The Starship core was designed with heavy mid-lane roll in mind. With only a moderate amount of asymmetry, this allows the core to pick up quickly in the mid-lane without consuming all of its energy in one spot. The low RG and higher differential help this core rev up quickly and make a big continuous shape downlane.
