Yes to swimming, but only if you can drown. I'm tired of the bs 'explanations' that you know magic that lets you breathe under water for indefinite amounts of time.... nor any magic scroll, pendant, curse, magic bubble etc.
It would be nice, for once, seeing your character with a gas tank or some odd diving gear.....

It just totally makes me go 'yeah right....' when I can afk my char under water :/
