Only those that have existed in more than one FF title in my opinion... Summoner or Beastmaster pretty much. Puppermaster as an abomination to me, and should have never existed in XI considering it was a class that never existed.

In regards to the other classes you mentioned... I'll quit, uninstall FFXIV and cancel my internet connection if they ever add jobs from WoW.

Traditional is the way to go, never fix what isn't broken.
