the sims 4 sims need major update

This is my exact issue with the game. The sims themselves are just so...dull. They are all the same because their personalities are dictated by emotions and not by their traits. There are so few jobs, traits, and aspirations anyway, starting a new family never feels like a new experience. I have my game so heavily modded in an attempt to fix the personality of the sims and the world around them and I still can't play for more than an hour, if that. It's just boring. Plain and simple. Which really sucks because I really want to enjoy this game. It's pretty, runs well, and has some really well done pieces of content (toddlers, seasons, cats and dogs)...but the sims are just too shallow for me :/

Edit: Hoping they could surprise us with a major overhaul to the sims themselves like they surprised us with toddlers but idk how likely that is.
