I just want to add my opinion that I like the idea of adding jump into the game.

I would like to be able to jump over the ledge from the 2nd floor and land onto the first floor.

It helps add realism, not the fact that you can land on ur feet and not break them, but, not being constricted to your feet and the ground, so you have to walk way around and down stairs and so on to get somewhere. I guess it would add more freedom would be the best way to put it. And dont we all want that in our MMO experience?
