You can world swap as most people are now aware, and things like the Orichalcum Nodes will respawn on the new server for you to harvest again. But the Jump Puzzles on different server clusters are also all unique.
At first I really did not like doing this jump puzzle. In the beta I spent a couple hours and didnt even finish it. However, the truth is, that once you know the puzzle well, it is very easy. It takes me only a few minutes to run through this puzzle now, and I hate jumping puzzles.
At the end you are rewarded with multiple blue prints, a lot of badges of honor and some random items. I now have I think 4 alpha golem blue prints. These cost 1 gold each. I think Bryt has several as well. The Alpha Golems can be Mystic Forge upgraded into Omega Golems, which are basically the equivalent of the first boss in Cadecus Mannor. They fire Missiles, shoot flames around themselves and generally hit very hard with a lot of HP.
By quickly completing the Jump Puzzle and world transfering to do it again, you have one of the only ways to farm much needed WvW siege blue prints, including what is needed to make probably the best WvW weapon in the game, the Omega Golem.
If anyone wants to do this but is overwhelmed by the puzzle, just say so, and Bryt, myself, or someone else can show you the easy ways through each part of the EB puzzle.
And remember, while it is very likely that mass orichalcum farming will continue after 'free server transfers' end, because of the guesting system that allows pve on any server, the EB jump puzzles will not be so accessible. The opportunity to farm these for free is limited.
