I didn't always get the complaints about the Ruby Sea sometimes. It's an ocean. Oceans are vast areas with very little life or activity except under the water. It's why there's such a thing as people going stir-crazy when they've been shipwrecked for so long out in the middle of no where.

Now, one thing I will agree with and accept is the gripes that there's also barely anything to do under the water. I think that's the main problem with the Ruby Sea. Not what can't be done above sea level, but what can't be done under the water if they're going to make a water eccentric themed zone.

We should have been able to explore sunken chests, explore underwater ruins, interact and explode marine life that's trying to kill us like sharks, giant squids, eels, etc...and have housing underwater!
