Forum:Dynasty Warriors Weapon

Um, hey guys.. I just wondering why Dynasty Warriors always change the EX weapon for each character.. such as Zhou Yu using sword and then staff, and Sun Quan swords change to Flame Blade, but Zhao Yun always using spear, and etc..

Why they didn't make the weapon just for character now and later.? I would love to see the character using an EX weapon from previous installment.. (similar like SW series when Mitsunari Ishida using Tessen from SW 2 - 4, Yukimura Sanada using Jumonji Yari)
