I doubt anything can be done about the traits unless they overhaul them, which I don't expect by now. Since the traits mostly give moodlets and don't affect behavior (and no longer even give new whims, in case of newer traits), they really don't make that much of a difference, which saddens me because it means sims I don't control are basically all the same outside of looks. I do think an interest system similar to sims 2 would help greatly and, since it would be a new system, I think it could be added. I also wish we add more aspirations, similar to what we had in Sims 3, but I doubt it will happen, and it's not nearly as important as working on the sims' personalities.
