Not an exhaustive list, but off the top of my head:
- No more limited time modes. There were some added temporarily for BFV which were fun but seem to be gone for good (they're not even available for Community Games).
- An expansion of the fortification system. If this was done in conjunction with increased or improved destruction then it could be interesting.
- Improvements to team balance (how Dice do this is beyond me though).
- Either an expansion to Community Games or a return of rented servers.
- Separate Core and Hardcore modes at launch. Trying to merge both together in BFV didn't really work.
- A well thought out assignment system. This did improve somewhat in BFV but it still feels too harsh to me and it deters people from trying to complete them.
- No more asymmetrical vehicles. They just seem to bring balance issues. Same goes for the perk system for vehicles, especially planes. It's brutal being a new pilot in BFV right now, going up against experienced players with fully upgraded planes.
- Keep the buddy revive system.
- Cut down on animations as it feels overdone in BFV.
Tanks that can drive through buildings properly and objects that can obviously be crushed or pushed away.
