Worst Expansion Pack?

Why the heck did this not come with a scuba diving skill...??

Also, I'm surprised to see GtW so far up! I just got that one during this sale and so far I'm really enjoying it. I've only played the scientist career now but it's a lot of fun and I like the potions and stuff you can make. For my next gen I plan to open up my own shop.
That being said I can see how you wouldn't really revisit the careers once you've done them.
