I scrolled up 100 posts and couldn’t find this post you’re talking about.
The idea that you can’t have reconciliation because of the Purge isn’t unreasonable in current lore solely because for reconciliation the offenders need to accept their wrongdoing, repent, and ideally work towards reparations, if you want it to feel ‘correct’. It’s not because it was “omg so bad”, it’s because Jaina still, apparently, doesn’t think she did anything wrong. Ditto for Vereesa. How can you reconcile with someone who thinks the thing they did to you was good? It’d be like if Jaina tried to reconcile with Garrosh the Unapologetic for Theramore. It just doesn’t work.
Simply sweeping it under the rug feels unfulfilling to the audience, which is a beef a lot of people have with the faction dynamic in DF. We got out of BfA and all of that and now they’re just kinda…friends and chill. Years (3-5) passed offscreen but we, the players, didn’t get to see any of that bond-building, so it feels cheap.
