Disagree on an attraction system, I've tried the mods with it in the past and don't like it. I like to have control over who my sims date, I wouldn't want it forced on my game.
As for personalities I agree I'd like to see some improvements. Biggest issue is with townie sims. Traits only seem to affect the sims you're currently playing with (moodlets) and have no effect on townies which makes no sense. For example I want to create vampire sims that are unfriendly and unapproachable, it makes no sense to have a dark and menacing looking sim who will just has a normal happy conversation with my sims. You can give them traits like loner, evil, etc, but it literally will not affect them unless you're playing with them?
If they ever add fairies to the game I hope better personalities come with them. I want them to be mischievous and tricky to talk to. I want them to be permanently playful and lively. What I don't want is Eliza Pancakes in a wig because at the moment that's what we'd get as every sim has the same personality.
