Personally, I don't think the MSQ content needs to be made harder. I disagree with the sentiment that it would force players to get better, Nidhogg, Shinryu and Titania didn't force players to get better, all they did was spawn endless complaints on the forums and social media.

However, I would love to see alliance raids, extreme trials and the earlier floors of savage get some teeth back again, those are all optional and wouldn't affect people who don't want to do them, they could stand to be harder and bridge the wide gap between the ease of the MSQ content and the difficulty of savage/ultimate.
