no one's life is sad because of the adaption of an entertainment fantasy show, no matter how it's depicted
I don't agree with the reshuffling either, a lot of it felt incomplete and rushed as it is, that comes with the need of telling the necessary story of a boring book. cutting out a few minutes of frivolous scenes won't change that. but we had that disussion since ros in season 1, in the end the success proved that d&d made the right call. if we got some book readers' vision of the show witthout some fun, gore and nudity it would probably have been too dry for such a massive success.
besides, I don't think it's unlikely that davos will still be sent to manderly, since we get euron in season 6 as well. it's not unreasonable to doubt that, though, he doesnt bring anything worthwhile to the table and is not nearly as interesting as other cut characters like coldhands, stoneheart, victarion and val.
