Threads of Fate?

Does anyone know if you have to actually do all 4 threads of campaign chapters? I’m already 54 and haven’t finished the first one because I’ve been doing dungeons that don’t seem to count towards the progress.

If I get to 60 can I just move on to end-game stuff, or does it make you finish the entire threads of fate campaign regardless, just like you had to finish the story mode at 60 before you could move on?

If we do have to finish all 4, they really need to change that or improve this mode. Random dungeons need to count towards any zones progress.
