And to take your example as the Paladin Highlord, your character doesn't have any army in BfA. If the Humans and Dwarves of the SIlver Hand decide, they will join the Alliance and help their friends, family and so on, your character has no power to stop them. They're not enslaved to your characters will. And the other "half" of the Paladin Order consisting of Blood Knights and Sunwalker will do the same. The Draenei Paladins will probably join the Lightforged. Thus, the already small, but elite, Army of your character will be gone. He has absolutely no option to tell the big factions on Azeroth what or what not to do. And more or less the same will go for most other Order Halls, they will either disband, stay neutral like the Druids and Shamans always do (Monks might fit in this category too), or will pursue their own goals outside of the Faction Conflict, probably what Warlocks and Demonhunters and such would do. Warlocks are another Order Hall, where it is very doubtful that they will stay together, without an overpowered leader who can keep them in check. Same goes for the Rogues, who might work together from time to time, but are also divided by races and factions. Hunters as well etc. The Death Knights might be the most intact, but they can decide too, that the Faction Conflict might be a good opportunity to satisfy their desire to kill, driven by their Runeblades.
The Legion will be weakened, but the Demons can become strong again, especially if they try and learn from the failures they did before. Use better tactics, becoming stronger individually, not being dependant on a Titan World Soul that can resurrect them again and again. Its also an opportunity to create new demon characters. We have races like the Nathrezim too, and potentially others, Zealots like the Shivarra or Sadists like the Succubus / Sayaad, who will probably love serving the Void Lords, using their powers. Archimonde, as someone who was only interested in power could, if he is still regenerating somewhere, join the Void Lords too. But i would prefer new demons, because characters like Archimonde and Mannoroth got raped by bad story telling and depiction, failing so often and much, that i can't take them seriously anymore, especially Mannoroth.
