For any other game, I would say I hate the idea of open beta carrying over to retail. But what with a lot of people already sitting with several level 50 jobs, I have no issue with it at all for 2.0.
Also I really hope that the community, if not the game itself, holds onto the party system that I love about FF mmos. I actually really enjoyed the 6 man parties in FFXI and partying up near the end of FFXI 1.0 if that makes me crazy.
