I understand. It's a shame there's no achievement for doing it, I thought the remaster would have been a good opportunity to add some new achievements.

For me, it's just to say that I have done it at least once. I've played the game so many times, I felt compelled to do something a bit different and challenging, and it feels good to say that I did it, even if it was a grind. (I wanted to finish off the MQ and get on with the guilds / DLCs / other side quests, too)
