Which element from a DLC should TS5 include in base game and what are replacing them for DLC

I'd prefer to see the basics done right next time such as all life stages, Sims awareness to the world and Sims around them, detailed traits, build and world editing tools, CAS loaded with features like color wheel body hair tattoos that can be placed anywhere and cars be the center of attention of the base game. But if they were to put in expansion features I'd like to see features that can be built up in expansions like clubs calendars and seasonal weather be there so every pack can enhance it I'm not calling for all the Seasons expansion activities to be in the base game.
