To add to the list,
- Reduce the number of parallels to less than 10. We don't need 50+ parallels just to appease everyone. Keep the player/set chasers involved in the hobby.
- No sticker autos at all. If the players can't sign all of the cards on card, then don't release as many autographs. This will keep the value higher in the secondary market which will actually attract more people.
- Only one 1/1 per player per card set (if it is required at all). No more Black 1/1, Black Disco 1/1, Nebula 1/1, Monopoly 1/1, Green 1/1, Platinum 1/1 etc etc etc etc.
Finally, Fanatics need to understand who are those who are in the hobby for the long haul. If they try to appease the latest 'in thing' they will run themselves into the ground. If you can please the collectors who have been around for 15-20 years and will still be here for the next 15-20 years then you will be able to withstand any criticism from those who blow out of the hobby as quickly as they blew in...
