We could say the same about the goblins without Gallywix, or the orcs without Garrosh. They're better off without their evil leaders who ultimately cared more about their own agendas than their people. The post-BFA treaty would not have been possible with these jerks still running around, which is why I ultimately agree with Blizzard's writing that the fighting eventually started back up again after MOP.
Yes evil leaders can drive conflict which drives story, hence some players criticizing it as "boring" but going in circles with the same evil leaders driving the same conflicts is also boring. Now these races are on a new path and I'm interested to see where it leads.
I like what we've gotten so far developing Calia, it really pleasantly surprised me that they acknowledged the multiple facets of the Forsaken as a people rather than just Calia's rather over-optimistic first impressions of "misguided dead humans who need her help." The new council structure for them recognizes that and I still maintain the best thing going forward would be using the variety of that council for some internal disagreements. Some things I can see them disagreeing on:
1) Calia in Legion helped the Priest order hall recruit deserting former Scarlet Crusade members. What are they up to now? Voss would be furious.
2) Yes, they've reclaimed a bunch of ruins, all well and good, we don't have to bake in Orgrimmar anymore. The Undercity is caved in and presumably still drowned in blight, should we build a new Forsaken-er Overcity on top of it maybe? I can see Calia wanting to rebuild the original building and preserve the historical significance versus the Royal Apothecary Society council member saying "no, it needs more black and green! I want slime fountains on every tower!" and forsaken members who were never even Lordaeronians in the first place wanting to just bulldoze the entire original building and leave the past in the past.
3) Sylvanas in Cataclysm resorted to using Val'kyr to zombify more Forsaken to grow her ranks. Both of them are gone now. While the Alliance/Horde war may be over, the point stands that they will eventually go extinct without something to replace this. What do we do about that? Should we do anything about that?
4) Should they keep expanding territory vs. what if anything should be given back? Calia seems intent on pulling out of Gilneas, which Genn is pleased with, but they also took over Hillsbrad Foothills and the Western Plaguelands. Not sure the humans want Southshore back in its state, but there's some ripe conflict regarding Western Plaguelands' rich farmland and the paladin presence there. Let's send someone they know, like Koltira Deathweaver to handle it! They have a history; I'm sure they can work things out. https://wowpedia.fandom.com/wiki/Bat...7s_Hope_Chapel https://wowpedia.fandom.com/wiki/Death_Knight_Campaign
