Yes.
I played in Edain, and many other mods and games refferring to Middle-Earth, wached movies (even "Born of Hope", give me back two hours of my life you filthy director!) and read some Tolkien's books, so mainly i know who is who and in which faction that heroe belong. But, there's many others who just wanna check out mod and what it offers, and they don't have lore knowledge. It will be easier way for them.
Also, I'm missing something, or Arnor don't have Hero killer? :x
(For that I always use my CaH, so I don't need it, but always - this is only faction which don't have HK, and it's sad a little bit.
)
