Well, I guess it's fine if the game has a fresh start. But as Nut pointed out, they are using the Lakshmi and UE rematch for the Avatar... which is why I also am assuming the game does not get a fresh start. In the case it is NOT a fresh start, missing out on all those grids could really hurt.. especially since we will soon be getting debuff resistant content from what I know.
However, if the game does get a brand new start, then it would be like you said, a good reason for people looking to start fresh. If anything, what worries me is that there isn't a "fix" to rate ups or raid servers. The only way to tell would be to wait for the official release and actually playing it to test it out.
