if we ever do get jump and or swim, it wont be till 2.0 end of discussion -.-

The current designed has no place for it, but maybe when 2.0 comes out, they will build it with both in mind.

I honestly don't want it though, I don't see the need for them, WoW had both, but there honestly was not need for them in it, they had some quests that you swam in, but they where the same as land quests, just.....swimming -.-
