Honestly, they just need to add far more feature toggles. If people could toggle every game feature they do not want/do not want to use that should help immensely. People "having to use MCCC" or other mods to remove unwanted gameplay is annoying—it should just be in the game options.
Removing things like phone call/text/dialogue clutter (which is in multiple packs), turn off paparazzi or keep celebrities in Del Sol Valley, occults to their respective worlds, or even keep all townies to their respective worlds reducing townie traffic to local or those not in world. Toggle off trait change prompts, likes/dislikes recommendation, etc.
Even a simple as toggle what worlds you want active or deactivated (per save file). A way to toggle/manage, and reduce autogenerated NPCs for roles. A way to tag remove/hide CAS/BB items from CAS and Build mode so the game isn't loading a myriad of items while creating/redressing a Sim or building, would I think help so much.
Usually people or reps say is "just deactivate some packs" to get better gameplay (or at least I remember that being a line in Sims 3). But with Sims 4 they spilt up gameplay across so many DLCs you can't just deactivate one type of thing.
Anyways, that is my hot take on the subject :P
