Guild Wars 2

Human
Warrior
0% speed buff

3 times finished in a line – at the last try i even got the chest on the way up

I dont know why it should be frustrating. You will make a progress and finally finish the jumping puzzle. Why should it be easy or possible to finish it within 5 mins?
That would entertain you 5 minutes .. wow.

There are enough player who already finished it – so it cant be to hard. Just dont give up.
Ah and one thing that really is good: youtube doesnt help you here :P
