As the first of several news pieces I'll be posting today, this change by ArenaNet won't come as a shock to many. Abused for weeks by exploiters and controlled by already powerful servers it’s no surprise that they will be removed. As to how Orbs will reappear and in what form no one is sure but if this change eases the game for many struggling servers and stops exploitation, it can only be a good thing. What a shame it is that ArenaNet have had to do it in the first place.

After a careful reevaluation of orbs of power we have decided to remove them from WvW in an upcoming build. As implemented, orbs tend to strengthen teams who are already winning and make it even more difficult for underdog teams to fight back. In addition, the current implementation seems to be irresistible to hackers/cheaters and will require significant modification to prevent cheaters from having an unfortunately large impact on the state of any given WvW game. Under the circumstances we believe that removing orbs completely is a better choice than attempting an in-place redesign/re-implementation as it will immediately put a stop to all orb hacking. It is likely that orbs, or some orb-like mechanic, will return at some point in the future, but only after we are confident that they will not exhibit the sorts of issues that we see with orbs today.
