Well the puzzles are nice but there are some quite annoying problems you notice when you try them.
First it seems there are some mesh problems, for instance I needed 10 trys for the first plank with winds of the jumping puzzle in Metrica Province. Because when I passed the winds and tried to jump from the plan to the floating island there always was some sort of invisible wall (most likely the stone there was somehow glitchy) which pushed me to the left and I fell down.
Another big problem is the camera.
Try the jumping puzzle in the sylvari starting area.
At least with a human character there are some points where the camera just stutters around making it quite hard to aim for the next jump.
