I created a similar thread in beta forum too. I didn't realize that the class was listed in the confirmation page for 1.0 char importation, so i confirmed and i couldn't change it after that 2 steps process. I wanted to keep the appearance so i didn't bother about all the options in confirmation page, 'cause i thought that it was only about char appearance and i did the error to confirm PUG as my starting classI already have my MNK at lvl 50 so i wanted to start with a lvl 1 class (ARC and ACN for me) so i wouldn't waste the early quest exp. This way all the exp until lvl 10 and more (i have to unlock airship if i want to go to limsa and join the Arcanist guild so all the main quest exp will be wasted as well) will be wasted for i am bound to PUG.
If they will reset those characters who had problems in beta 4, why wouldn't they reset ours as well? I don't think there are lot of people out there that want their char wiped, so it's a matter of.. 10, maybe 20 characters?
