I wonder what Bungie is going to do with Savathuun and her Lucent Hive. They must still have a part to play. They'd be great allies, if they could stop acting like typical Hive for five minutes and have Savathuun start acting more like a strategist and stop being a deceiver who can't be trusted.
The Cabal and Eliksni have joined us, now all we're missing is a Hive and Vex faction.
Edit: Because Savathuun doesn't have a worm to feed anymore, she doesn't have to follow her nature. She CAN pick a new destiny for herself. Bungie just has to get on top of writing her redemption story.

Yet another thing Bungie hypes up for an expansion, just to drop them as soon as it's done and not come back to them for years. Throw them in with the Scorn, Nightmares, and the Fallen using Stasis.
