I mean it’s going to be a rather large undertaking with the new talent system changing how abilities work in various ways, all the new voice lines and animations, probably new cinematics. I think it’s a lot more than “Archives, but bigger” that people like to say it is.
Not saying I’m sold on it, just saying I think what they’re adding is larger in scope than people think. They do want it to last, after all, most likely for years.
