- The Follow Me feature, needs to return. I was really let down by the fact that BW/BW2 didn't utilise this feature and I'm sure many many people liked it.
- The Dream World...needs to go. I found it quite banal to be honest.
- Hidden Grottoes have to return as well! They're great to randomly encounter, I just wish the chances of finding a Pokemon in them, where increased.
- Secret Bases! I loved these in RSE, so I'd more than welcome their return. They're fun, and serve as a great time killer from the main plot.
- The Underground, while fun at first, got boring and repetitive. So if it were to be improved, I'd definitely welcome it as well.
