I totally support all these things. I think climbing over small rocks a la Call of Duty would make more sense visually than contextual jumping too, so I'd like climbing to be incorporated alot. Also, imagine the new dimensions it could add to exploration? This is an MMO after all, exploration should be on of its key features. Why make a huge world if it is only to be utilised in a very monotonous way, i.e., by walking all over it.

I would like swimming just as much, however, I'd like to point out that Crystal Tools Engine cannot render water worth a damn, so I'm sure we will never see swimming until the engine is improved.
