I'll be honest, when I heard about having the 3 alliances working apart on separate paths back when they first announced CT, I was not expecting... Atomos.

I enjoy CT heavily, and even run it when I've exhausted my one drop for the week, but I would love if they had done more with the separate groups sort of how you mentioned. Or perhaps progress on different paths, far apart from one another, and converge again for a boss.

It might be a nightmare to balance such a dungeon, but I'd be all for it!
