Zenos has far outstretched his welcome. I could understand if they'd done this sooner. But they haven't, he's always liked doing things for their own sake. Hunting just for the sake of hunting, finding a foe mighty enough to trounce him and give him a little ecstasy while he's at it. I don't really want the developers spring-boarding him back into action for character development. Something that should have occurred 2 expansions ago. He was forced on us in his resurrection and all things considered I genuinely think his screen time could have been developed on something more significant than just a bloodlust.

As for Meteion, she could serve as an interesting one. If anything, to see the world and future that looked despair in eye. Or as serving as an extra source of information for parts like Akasha/Dynamis. It's cliché, but it would work a lot better than more Zenos rammed down our throats.

But all things considered, I would actually like to see Y'shtola be our next companion. I know she is now and all, but her whole want/desire for the ability to traverse the shards, this in itself can lead to some brilliant stories, bringing some meaningful closure to her character. I would like to see them really just work on completely tying up their characters going forward otherwise it's going to be something that just... lingers for years to come.

After that, I'd really just like to see an entirely new cast on the table. Something to truly set the stage anew without that attachment of the Warrior of Light, and all the consequences that come with the title. E.g. A constant or incessant mention of how busted we are in the face of anything walking the star.
