He got blown up by Malfurion's wisp army, which would've sent his soul to the nether.
Presumably, he was still in the nether when we went back in time in CoT. When we went to Hyjal, there was an Archimonde physically there. Now, at that moment, if nether time is not anchored to our own time and operates irrespective of it (as the Draenor situation would suggest), does that mean that there was an Archimonde in the nether and a different Archimonde on Azeroth at the same time? (Worth noting; this would apply to any demon, and I only use Archimonde as an example because he was in a specific place at a specific time. We can also use it as a general "what if" to explore the implications of an all-timelines/realities/whatever Legion or Nether)
If we say yes, then that'd mean there's many copies of each demon from different timelines (where they died in the mortal plane and were sent back to the single, not-on-our-timeline nether) and we'd have to have some kind of system that re-unifies versions of a demon when they get back to the nether. Or, there'd have to be a single version of a demon that's the "real" one that goes back to the nether, whereas the others are shit outta luck.
We could say that no, nether time actually is synced to our own time (meaning that going back in time in our own world also goes back in the nether's time), which then then eliminates the problem of duplicates (as by going back into the past, we're back in the nether's past too). That raises another difficult question, though; if the nether is synced to the time that you are in, why is the Legion that's up-to-date with us getting summoned in Draenor?
Then, we can explain that by saying that Draenor is a different kind of time travel with different rules (which it is, as we already know) which then raises another question; does that mean that the Legion is synced specifically to our timeline? If so, does that mean that it's more accurate to say that our timeline is the only one in sync with the nether, acting as a master record of what's going on at any given stage?
Then we've got all the questions about why the Legion keeps coming back in sequence with our own timeline, why they don't have precognition or supposedly unattainable information about various things (as they did have in Draenor 2.0, but not in other examples of travel in time or timelines) and why none of the other potential problems with a single Legion have come up.
Time travel is always a bit nonsense when it comes to applying reason and causality, but the existence of only a single Legion is just impossible to reconcile. To me, it only really makes sense if the Draenor Legion was simply our Legion instead, or if the nether we know is rooted to our own timeline but has access to others (which'd require further reconciliation to explain why the Legion got through to Draenor 2.0 anyway). That's why I don't think that can be the case.
That's why it makes a lot more sense to me that Draenor 2.0 would simply be a thing that exists somewhere within our own timeline, timeframe and reality, with our own Legion accessing it in a similar way to how we did (and Kairoz's actions being less about travelling through time/timelines and more about copying something from another). It eliminates the messy, endless complications that arise from the Legion being in every version of everywhere and operating on their own sync. Again, not actually supported by any sources that I know of, but I just can't rationally reconcile the Legion interacting with time and timelines the way they've suggested that they have.
