I think he meant that he enjoys stuff like the MNK dance, not that he wants to get away from them. Everyone could just play BRD.
As someone who's totally given up on endgame, I can't comment much on the specifics of Coil. But I think that in general, nerfing old content to give people a crack at it is good practice. People who really really REALLY care can look already up the date you got your clear achievements on the Lodestone anyway. But making old content into a "solo" mode would go against making the game worth playing with other people, which should be the very point of an MMO. I've got plenty of games to play if I don't want to deal with other people but when I'm enjoying an MMO, I want to talk and be social while playing together.
