Sacrosanct
Legend
Odysseus is one example. Sure he's a badass fighter - but if you put him in a party with Achilles or Ajax, he would be overshadowed in straight up fighting.
King Arthur vs Lancelot would be another. If they are both fighters than Lancelot would be higher level, so they wouldn't be in the same party.
Tanis Half-Elven from Dragonlance, he was a fighter, but his skill with arms was never a part of the character which was ever much emphasised.
Basically any mundane leadery character who can hold their own in a fight but is not necessarily the most badass figure around.
“Not the toughest fighter in the party” and “person in charge” isn’t a warlord though. Not in DnD terms. What did all of those people do that emulated warlord features? Specific examples. Because all of those people were just essentially fighters with higher CHA or WIS otherwise.
