This is a difficult question, but I will try to limit myself to three things.
1.
Actions should trigger reactions. I would like the game to actually consider my input. If I make Sims fight, they should stay mad at each other until I decide that I want to try to make them friends again. A shy Sim should not go out in public and make tons of friends as if he/she isn't shy at all. I would like to see him/her struggle to make friends.
2.
Redo everything considering moodlets, whims and aspirations and add likes and dislikes. I would like the whims to better represent my Sims. I preferred the Sims 3 and Sims 2 style, were Sims could get wishes to marry or get children. I would really like to get that back. Whims should be related to the things my Sims do and to their aspirations. Besides all this, I would like a system were we can specify our Sims' likes (and dislikes), from their (least) favourite food to their (least) favourite colour, their (least) favourite activities, etc. These likes and dislikes should also influence their whims/wishes and moodlets, so a Sim who hates sports, might not want to go to the gym and get a negative moodlet if he/she did.
3.
Redo the teen life stage. I would really like better teens, that feel more like teens. I would shorten their length and add a bit more childlike facial features. And I would like new animations for them, like a gangling walking style.

5. Collectibles - simply more gems and cuts (I miss pink diamonds with it's crazy chance to find).
I really miss those cuts too. Collecting all those gems in all those cuts was something I did quite a lot in The Sims 3. I still don't understand why we don't have gold or silver and instead have all those fantasy crystals and metals.
