I honestly agree. Personally I think we have more than enough 'stuff'. I think it's high time to get the foundations improved so the gameplay can be more enjoyable.
The sims themselves are just all over the place. The emotions, traits, whims and aspirations systems are so wonky. Emotions need to be way less overpowering, traits need to do more than add moodlets and a few specific interactions, the whims need more depth than "buy this, buy that", and aspirations shouldn't just be new pack tutorials. And most importantly, babies are in serious need of an overhauled so that they are living sims instead of objects with needs. There's no reason we should be able to carry our pets around and not our babies. Elders, children, and teens also are in in desperate need of attention, because as of now, they're all ignored while YAs continue to get all of the gameplay while the others have nothing to make them stand out. Its a serious problem when toddlers are the only life stage that feels semi-unique, but are still ignored in the majority of content. I can only pray that it changes this year.
