None of the traits are worth salt in this version of Sims it doesn't add much and where it subtracts tends to be around flaws with either the AI or game design. Some might even say 'Bad AI & Bugs' is a flaw your sims have that's already in the game!
The trait system in general lacks consequences, depth of personality change, and activity(world interactions favored by the trait system).
Also I'm not very fond of the idea of making something that already exists in the game mandatory. Some people will no doubt feel different than you and want different things for their Sims.
