Yes, I'm disappointed about this.
I love and play the Sims 3, and it's not a matter of wanting the Sims 4 to be exactly like the Sims 3. Since I'm playing both games at the same time, I'm happy that the two tropical packs offer different things. I wouldn't mind it if diving wasn't in IL at all. But since it is in the pack, I would be happier if I could see my sims do it.
This doesn't affect my enjoyment of the game. The Sims 3 Island Paradise was what brought me to the Sims in the first place, and Island Living was what made the Sims 4 finally click for me. I'm enjoying it very much. But it's perfectly normal for dissatisfied players to express their dissatisfaction. No one has to be "humble" towards a rich and powerful company.
