Predictable? Sure. You could also have predicted that Ciro would kill Riltia...but he didn't. Besides, I'm not sure how "predicting" the possibility is germane, but I've also mostly forgotten what the root argument was about.
He didn't,
this cycle. As for other cycles, who knows?
Predicting the possibility is relevant because people were saying "the guys in charge have noted there are anomalies this cycle, the whole system is in danger!" when we have no real reason to believe that anything that's happened could cause that. If something is an easily predictable- even if uncommon- occurence, it's that much more likely to have been factored in by whoever set up the cycles in the first place.
Oh, sure, some are more important than others. But none are unimportant, not to Oric, not if he's thinking...um...the way I would if I was an evil overlord in some kind of dungeon.
Important to Oric, perhaps, but who says he's the one in overall control of the cycles? The flash minigame suggests he's simply the current warden, not the only one who can do the job, and that replacements are built in to the system, so him losing control is not likely the end of the cycles.
before I used that to support a theory that the dungeons somehow autorepair.
I'm not saying that the dungeons must be autorepair, I'm saying that they can be quickly and easily remodelled on a very large scale. Whether that was done by Oric, Proxxy, the Angels, the Dungeon itself, or someone else entirely doesn't really matter.
the Greens, which seem to be a life-support system, are in the Underside. That would evidently spell doom for the entire complex within hours.
Remember how I said the Underside may well not be an original part of the Warrens? If they did get added on, they would need their own life support.
Dorfliw, Nightmare Knight encounter confirmed! Think we can talk him down when we see him?
That depends on whether we have Al with us.
