Yeah, we're working hard on getting stuff finished off; you won't have to play all the way from the beginning again though, as you can access earlier saves, make different choices, and get different Ideals as your highest.
Once everything's in, beating the last boss will also give you an Ideal choice to push things over the limit for things if you set it up that way, so if you just wanted to farm endings, you could do it that way, too.
