Buying packs and intentionally not using the main feature

I have Vampires and only played as Vamps 3 times. I love the pack content though.
Stars Wars ... I have never taken a Sim to Batuu. The stuff from build/buy is used a lot. The floors, plants and the toys. Also has nice looking trash can. I will go to Batuu one day when it fits into my storyline.
Parenthood and Dine Out are disabled most of the time.
Eco Lifestyle is turned off in options. I use the content all the time.
I have only played with magic once but use the windows/doors a lot.
I could go on but I don't feel the need. Everyone is different and makes different decisions based on different things. Just be true to yourself and make the final decision. I hope my input helps someone.

I mainly buy a pack for objects. I see my pattern. For me gameplay is a bonus and not always used. It's too much for one Sim. I have played or will play everything at least once. Will revisit some stuff if I want to. It's my game and my money.
