I miss the orb defenses and takes in WvW. It provided a focus for battle and strategy as well as something to care about that was not just a capture point flipping battle. I do not miss the the unbalanced results of a single realm having all the orbs, the exploits, and the bugs.
Perhaps there would be some way to put a value on possessing the orb on the map it is on without spreading the orb bonus to all maps or making the orb bonus something useful that does not over power the holders.
