Currently the Xi'An scout isn't matching the description it was given as the nimble, race winning fighter, when will it be brought to it's proper advertisement?

For racing maybe a slightly higher SCM speed, but it's agility it's quite good and where they want it. They know there's an issue with weapons in it and the targeting makes it difficult to hit, but they'll resolve that. Also with racing the tracks were designed before the Scout came into the game.
