I am happy with all we already have. I haven't explored some trait grom all EPs yet, not even give some of them to my SV Sims who ageing up with another slot to full. That being said, if you ask and I would need to want something new, I would like "Intuitive" and "Poetic" as well as "Dominating" and "Submissive".
"Intuitive" Sims would sens other Sims moods and act accordingly, they would "feel" or "know" before something gonna happen, like Meteor etc. Like gut feeling, moodlet. They would intuite things, animals and fellow Sims, haha.
"Poetic" ones would of course benefit in writing and careers, which favor writing, as well in Film industry (movie directors) and in Music area. They could write poetry and publish it, write plays to be played in Theather etc.
"Dominating" Sims would love to hang out with "Submissive" ones. Their need to dominate could express in wanting always winninig an argument, being bosses in work faster, all a out being leader etc. On the flip side, the would take very hard if they fail to dominate.
"Submissive" would be the non assertive ones, followers of some sort. They would always submit to "Dominating" ones. They would make good workers low in career ladder and struggle more to go up from level 6. At the top they would feel exausted fast, but they would make exellent company for more active Sims.
Ahh, and the idea of "Pathological liar" is great too, as well as "Always right". I love the bad traits. I could add "Narcistic" and "Easly pissed of".
Maybe few more like:
"Trend setter"
"Stiff"
"Sweets eater"
"Meat eater"
"Grilled cheese" haha
