playing the objective like a real gamer not to their KD ratio
@PugJesus Where'd they get 500 elves from? I don't remember that. Lol

Iirc, it was legolas and 2 other elves that joined after the battle (elronds sons)

The other archers were humans

No, Legolas was the only elf at the Battle of Helm’s Deep.
Thats what is said, the other two joined AFTER the battle

True, though your comment was a bit cryptic.

I feel we really missed out, by getting Lorien elves instead of Dunedain rangers. Ofc they wouldn’t have been in such a prominent battle, like Helms Deep.

Though, actually they could have been placed quite well. I always disliked the army of the dead fighting at the Pelenor fields, in the movies, since it invalidates all the struggle of Minas Tirtith’ soldiers and Rohan‘s riders.

It’s way Vetter in the books
Hey, Legolas is a prince and hardly just some average elf. You shouldn’t expect all the other elves to perform to the same standard.
You can tell it’s a work of fiction because most of the royalty in LOTR have some outstanding qualities and aren’t all inbred.
In medieval and antique Europe, royalty and nobility in general was often expected to fight on the battlefield. It was only in early modern times when gunpowder and pike squares started making cavalry charges obsolete that this fundamentally changed.
