It's funny how different people react to certain changes! I thought Perrin's accelerated arc was an inspired choice, although I was a little uncomfortable with the 'disposable wife' vibe (it would have been good to see more characterisation of her).
My strongest disagreement is actually on #10 - Jordan was writing post-sexual revolution and quite unequivocally portrays a more libertine view as being enlightened; remember, Aviendha *laughs* at Rand when his immediate reaction to their hookup is to propose marriage - and Jordan portrays Rand's eventual, er, arrangement quite approvingly (I get the impression Sanderson was rather more uncomfortable with it).
Now of course we've moved on again, so you might think the update is useful to allow the show to reflect our world. But to be fair there's some sophistication in the books here - in a world without reliable contraception, this is really a matter of life and death for women. In Emond's field this means people disapprove of not waiting until marriage. In Aiel society that's unnecessary: strict rules around 'obligation' mean that there's no need to worry.
Even so, the main objection I have is this: it's important that Rand and Egwene are not in love! They are from a back country village and have sort of just assumed they will marry because it seems *convenient*. But really they are just friends: the care for each other deeply but don't have that particular spark. Having their relationship be more advanced turns it into a breakup story, rather than one about how they realise that there's more than one way to love.
