I'm trying to make myself stop caring about changes from the books, even the ones that don't seem to have any plausible reason, but even then, their alternate universe version of WoT should still have internal coherence and some attention to the bigger picture, and we're not seeing much of either.

For instance with the Bayle Domon scene - I don't mind in the least that they dropped the idea of the Illian accent and I can't say I noticed the throwaway reference to a racehorse. But as you say, that negotiation was just stupid. If he was going to drop the price of the poem as a gesture since anyway the serious money would be for the cuendillar piece, obviously it should have been a package deal for both in which 'oh, I'll only take the poem then' wouldn't have been an option. Or at a minimum, would have been an option only if Moiraine used her Aes Sedai status to intimidate him into accepting it against his will, making it essentially robbery (and we'll assume for the sake of argument that in this alternate universe, Aes Sedai like Adeleas and 'Verin' do permit their stilled ex-colleagues to keep acting like they're still Aes Sedai...).
