Are you disappointed that diving is just a rabbit hole?

Disappointed, yes, because I have a passion for sealife. But it would have been at the expense of something else, and I like that the pack isn't only about what happens in the water but appreciates other aspects of what an island is. I suspect that I'd have ended up disappointed one way or another! Overall, I'm enjoying the pack; whatever people are saying it lacks in gameplay must not be my playstyle ¯\_(ツ)_/¯
