Fishing reinstated as a class, and the mini game brought back.

Being able to mail items and gill to another of your characters.

I know they took that out to deter gill sellers, but really, it doesn't bother them at all to meet in person like a bunch of back alley crooks. I was a GM for another game once and it was a lot easier catching gold sellers when they used the mail, just look at the logs for millions of gold exchanging hands and a message simply saying "your order"
