Would Simo work better as Archer or Assassin? Nevertheless of what class he ended up in, his fighting style is a hybrid of both anyway.

I'll give a list of heroes I believe are underrated so chances are you haven't heard of a good number of them:

Hang Tuah, the greatest knight of Southeast (Saber)

Rustam Farrokzhad, the Persian Heracles (Rider, Berserker)

El Cid, Campeador of Valencia (Rider)

Tomyris, the Queen who felled Cyrus the Great (Lancer, Saber, Archer)

Tiresias, the Blind Seer (Caster)

Mochizuki Chiyome, Leader of Kunoichis (Assassin)

Olga Prekrasa, Fair Princess of Fire Birds (Assassin)

Hanuman, Hindu lord of monkeys (Saber, Berserker)

Yamato Takeru, Wielder of Kusanagi (Saber)

Okuninushi, First Hero of Japan (Lancer)

Dobrynya Nikitich, Dragonslayer of Russia (Lancer, Rider)

Houyi, Feller of Suns (Archer)

Boudica, Queen of Rebels (Archer, Rider, Berserker)

Utnapishtim, the Eternal Sage (Caster)

Tamar of Georgia, the Deified Queen (Lancer, Rider)

Herod the Great, the Mad King (Assassin)

Arngrim, Viking of the Blood Sword (Berskerer)
