Fun fact : Leona and Xing Cai share the same voice actress.

Besides that, Warring Kingdoms skins are based on iconic looks of real people from the Warring States period of China, and the Romance of the Three Kingdoms.

Xin Zhao himself was based directly on Zhao Yun, while Guan Yu and Lu Bu have very iconic looks (long beard with red face, and halberd with long-feathered headress, respectively).

If Riot were to make more WK skins, it'd be based on iconic looks, not direct copies from Dynasty Warriors, unless they're fine with Koei suing them.
