Has anyone ever figured out what this thing is for, or why it is there? For the uninitiated, I'm talking about the portal at the jump puzzle before the Gatekeeper checkpoint. A second set of jumping platforms can be spawned that lead out to this portal, it has to serve [b]some[/b] purpose. I have to wonder if it leads out to the portal below the initial entrance to the Vault (where you form the spire)? Edit: This community is disappointingly unimaginative. I have been playing since the alpha. CoD try-hards need not respond to this post. Edit 2: Thanks for the replies, non-trolls :) I agree that it may be tied to future DLC content, and/or the "third tier" Vault of Glass raid. The theory of portals being the original version of raid checkpoints is interesting, I hadn't heard that one before. Hopefully we will find out one day!
