Any issues arise when skipping campaign at 60?

On my alt, just hit 60 and am still in Ardenweald part of the campaign. As I understand it I can now swap to Threads of Fate and autocomplete the rest of the campaign. I’m a little hesitant as it’s a new system and prone to complications, such as

  • loss of rep gains from questing (not a huge deal)
  • getting locked out of prerequisite quests
  • I know this sounds silly but it will bother me if the campaign quest achievements forever say “not completed on [character]”

Can anyone who has done this verify whether they noticed any such problems?
