Which Sims 4 Pack do you regret buying? ⛈️ (And why so?)

I regret buying Discover University, even at 50% off. I don't like enough about it.

You either have to grind unreasonably hard to graduate within a reasonable time, or you have to drag it out for weeks and weeks. You can't move your sim into university housing without completely severing them from their household, which often conflicts with legacy-style play. You can't pick the roommates. You can't follow your sim to class;  so many rabbit holes. The gatherings are lame. There are no uni students unless your sim is actively attending uni, so the world is dead most of the time. NPC students never graduate.

The bb is clunky and ugly, and I have a hard time matching any of it with other bb. I do regularly use one potted plant, one bookcase and the ping-pong table. So that's three items I can find a use for. Yay.

The cas is super hit and miss. I use the hairstyles, but maybe only half of the clothing.

And the world... ugh. What a waste of space. As I mentioned, there's no one in uni most of the time, so it's just this empty, dead place with a few NPC households sprinkled around it. My sims hardly ever go there. I wish I could at least repurpose the campuses for other things.
