What would you like to see that most likely will not happen

Mostly I just want to see features from past sims games returned that somehow still have not been added back yet, many even where in previous base games.

Sequels are supposed to improve on the series after all. It's why it's especially ridiculous that we only get three traits on sims in sims 4 and that these traits do far less than they do in sims 3.
Sims will just ignore it, like vegetarians keep eating meat on their own.

They all just seem to have this same shallow punchable hipster personality.
