They always overestimate the downtime these days because when they go up earlier than the estimated time, it looks good for them even if it is transparent.
But long downtime to implement a feature that reverses something that has been in the game since day one(faction conflict)? Sounds normal.
I would much rather they take their time in making sure things go right then to have them rush this only to log in and have the game crash and be offline say for a day or two like it was way back.
Do you honestly not fathom just how huge cross faction grouping is? The level of changes needing on both the front and back end of the game to implement that? I mean good grief it’s probably a much larger deal than literally 9.2 or 9.1.
It’s really not anything new for content. People who choose to not engage in cross faction will notice a few things. All Torghast wings open…that existed before.
And honestly I don’t think there is much more. The new arena is meh and no on does arena. The new M+ season isn’t for a month or 2. The renown thing is now good til 60 so thats something.
