1. Planes !! (I assume the main reason for the lack of them is streaming issues, as it already has issues with the chopters)
2. Purchasable safehouses
3. Snow
4. A warning before you get slapped with a large wanted level for going into the wrong area (I accidently strayed into Alderny in a helicopter mission)
That's about all I can come up with
Small fixes:
1. Subway map in game
2. Marks on the map showing you which buildings you can go in (can you go in the rotterdam tower?)
3. The ability to leave notes on your map for little things, like an armour supply
