Are you disappointed that diving is just a rabbit hole?

Not really, as I found diving to be pretty lack luster in S3. Lucrative, but pretty boring. Pretty under the water, but after a few times diving I was pretty 'meh' with it, but hey at least the option was there if you did like diving. I would have figured any deep diving of sorts would have most likely been a loading screen to a underwater lot of sorts for diving specifically.
