I would recommed the Liberty Dreadnought, Bretonia Battleship, Hessian Battleship, or Mako. All of those in skilled hands can kill Heavy BS. Liberty Dreadnought is good overall, same with Bretonias. I personally have both Bretonia and Liberty, and I love them. Mako is a little hard to use since only can fly in Oicrons and Omegas, and its oppopnent is the Osiris, Legate, and Marduk. The Valor is a nice ship no doubt, but a skilled Bretonia BS pilot or Liberty, will kill it.
