Gotta love it when people act like something is worthless because it doesn't appeal to them personally. Well, I will never play Hrothgar so adding them must have been a waste of resources, I guess. I don't like crafting so all the new crafter content is worthless? Savage, Ultimate raids?
NG+ isn't for everyone. It's for those who want to replay the story - cutscenes, out-of-cutscene dialogue, fights and everything else - in its entirety and not because there's a carrot on a stick. And that's fine. I'll be using NG+ to play the story again many times over as different classes and maybe even races and genders over time (without having to level an alt, hallelujah) so this is a worthwhile addition to me.

There are many other things you can do in this game to feel "rewarded" and to level alt jobs.
