I watched recently a french video about the useless activities that the players in Guild Wars 2 can do if they want. One of them consists of jumping from a high place and do the same moves that the olympic swimmers do in competitions. I had to go in Lion’s Arch anyway so I decided to give that one a try.
When you get in that area your character suddenly wears a swimsuit and a pair of glasses. And when you jump, you get access to certain skills allowing your alt to do the same moves than the ones in competitions.
Here is my Asura guardian who looks all professional with his mini-pet golem that I got from my Hall of Monument in Guild Wars.
