Education Packs: I think they need to add incentives for the graduated sim though, slightly increasing raise for the graduated sim is not a game changing, an ability to progress career level beyond lv 5 could be added for those who attained the degree required for the career, and high school graduate can only go up to lv 5 and doubled the requirements to get promoted to the next career level except A student, and high school graduate need to take an interview and test before they get the job similar to aptitude test for university in sims 3 or audition in get famous so they need to have the required skills before they can get a job, university student on the other hand get a free pass if they have the degree.
But I don't know whether simguru read their own game's forum because it seems they prefer to answer questions or maybe read suggestions on their twitter accounts than here.
