(Please forgive the massive edit, I somehow hit "Post" in the middle of writing my post.)
A lot has happened indeed!
- The Shiny Charm Box, if that's what you meant, is not entirely useless; you can trade it in for some shiny charms, which will not disappear anymore. Or, you can hold onto it and it may become very valuable and sought after by collectors of legacy items.
- RMT is indeed forbidden now. You can read about it here
There's a bunch of other things that aren't crossing my mind right now, as I've forgotten what it was like several years ago. I think someone else may be able to chime in who has a better idea about the changes that have happened.
