Sorting the warriors for a Tabletop

I'm putting together a table top thing for me and my friends and needed to put the warriors into style groups for gameplay purposes. I wanted to sort them based on their actions and personality in the games.

Vanguard for the fighters who are the first into battle seeking glory.

Guardian for the protectors that are immovable in their defense of a person or place.

Tactician for the brilliant minds that enact strategies to bewitch and confuse foes.

Commanders for the charismatic lords that lead with care, respect, bravery or cruelty.

Legends for the warriors that inspire Tales and warriors alike with their incredible deeds.

Wu Wei Shu Jin Dong Zhuo

Vanguard: Sun Ce Xiahou Yuan Zhao Yun Zhong Hui Hua Xiong

Guardian: Taishi Ci Dian Wei Zhang Fei Xiahou Ba Zhang Liao

Tactician: Zhou Yu Jia Xu Zhuge Liang Sima Yi Cheng Gong

Commander: Sun Quan Cao Cao LIu Bei Sima Zhao Dong Zhuo

Legend: Sun Jian Xiahou Dun Guan Yu Sima Shi Lu Bu

Toughts on other characters? I know some are easy like Yue jin being a vanguard or Zhou Tai as a guardian, but what do you all think about some of the harder ones?
