I think that was the jumping puzzle the media first had access to. At least the scenery looks familiar to a video a few months ago. I only watched the first few minutes, I want most of it to be fresh for me, but I can tell you right now... BRING IT ON!!
I love the Vistas and am a little disappointed when they are simply walking to a ledge. The Sylvari jumping puzzle was an excellent balance of challenging yet simple. But I understand not everyone shares my point of view.
AJ and Fire Walker have had almost a year's practice with jumping in Star Wars, so they're pretty good at it. Personally, I love the jumping puzzles but I'm lousy at them. Jumping is fresh to me and the controls still feel alien so most of the time I get stuck on a ledge with the camera facing the wall or the sky. In GW2, i'm struggling still with the camera controls. I got used to the camera auto-moving to face the direction you're facing and it doesn't in GW2.
I do enjoy attempting the puzzles though and I think with practice I can master them. Just give me some time. Lots of time.
.....And whatever is in that end chest had better be AMAZING!!
