All of that faceless men talk was purely speculation pulled out of nether regions. the books haven't really went into any detail explaining how the pricing structure works, other than they are expensive, the show has merely postured that it would be cheaper to hire sellswords than a faceless man. The waif's story was just a story, the game of faces, teaching arya how to lie.
All we know about the faceless men is that they began in Valyria. The slaves working the mines under the 14 fires were under such shit living conditions that they would sometimes pray for death, and eventually another slave decided to fulfill their wish. Eventually a slave got smart and prayed for their master's death instead of their own, and that's when the whole "assassin" thing started. Enough slaves escaped/freed/whatever over the years and you know the escaped slaves fled and founded braavos, and the faceless men established their order there.
They are a religious order, they answer prayers, if that prayer is for death (either your own assisted suicide style or the death of someone else). They worship death. If it's your own death you seek they simply take your face, but if it's someone else's death you are praying for, I doubt they charge based on someone's ability to pay, more like they charge based on the sincerity of your prayers (this ties in to how that person has wronged you) and the difficulty of the kill.
can we go back to talking about stannis and why some people are butthurt and he's like, no longer the mannis?
I get some book purist's are mad, not because of the scene, but because immediately following it, inside the episode they spoiled that GRRM told them about the scene. Some interpret it that they spoiled Shireen's death (by mel/selyse), some take it that they spoiled that shireen dies at stannis hand. Arguments can be made either way really.
But really I don't get the hate? Other than telegraphing that this scene was going to happen all season, both the books and the TV show has foreshadowed this sacrifice being made for 4 books/seasons now. this is and has been stannis' arc the entire story. I don't understand where the confusion comes from?
Immediately following this scene he confirms to davos what he saw in the fire, he saw the great battle in the snow.
from the books:
I never asked for this crown. Gold is cold and heavy on the head, but so long as I am the king, I have a duty ? If I must sacrifice one child to the flames to save a million from the dark ? Sacrifice ? is never easy, Davos. Or it is no true sacrifice.
? Stannis, to Davos Seaworth
Lord Seaworth is a man of humble birth, but he reminded me of my duty, when all I could think of was my rights. I had the cart before the horse, Davos said. I was trying to win the throne to save the kingdom, when I should have been trying to save the kingdom to win the throne. ?
? Stannis, to Jon Snow
The more we bleed each other, the weaker we shall all be when the real enemy falls upon us.
? Stannis, to Jon Snow
Demons made of snow and ice and cold. The ancient enemy. The only enemy that matters.
? Stannis, to Samwell Tarly, Melisandre, and Aemon
