Underwater swimming and combat is one of those tetchy subjects that people seem to have strong opinions regarding, even though I personally don't think it makes much of a difference whether you can do these things or not. Games that haven't had underwater combat didn't make me miss it, and games that had it made me feel like I was flying very, very slowly.

So let's tack this today: Does underwater combat really add that much to an MMO? Is it a waste of developer resources or an important part of creating an immersive world? As a bonus question, when's the last time you went underwater to fight jellyfish with a spear gun in the real world?
