Not a bug but wanted to get opinions on this -
How about unlocking certain character locked items (wings, halo) specifically. This would promote users to create and play the game longer since they can enjoy different classes without having to re-create these expensive items again and again. Playing the same class can get boring...
Another option would be to implement a service or item that changes a character's job class.
I know there are players who would pay a lot of diamonds for this. I'd be willing to pay at least 4k diamonds to change classes myself!
Thanks for any feedback!
