tomorrow during the weekly update they might drop the new October roadmap, which should give us a preview of the Halloween Event/Iron Banner stuff.
or I'm wrong and they won't give us shit. ¯\_(ツ_/¯
I feel like they would have already released an October roadmap given we're at the first week after the last roadmap already. Probably too late.
My hope is this:
Tuesday, 10/10 - Iron Banner
Wednesday, 10/18 - Leviathan Prestige Difficulty
Tuesday, 10/24 - Festival of the Lost
That would pretty much line up with what they did in October 2017.
