I hope class changes are in. I know things got delayed, but I would have hoped the delay was merely 'when to activate' and not that 'we did not have enough content to begin with'.
But I also understand even the new player experience/leveling change/chromie time is a big enough fundamental change that can invite lots of wacky bugs so it would make sense being a small start.
Just dammit I really wanna see all the changes Shadowlands is bringing in, especially with the classes.
Also, hope to get datamined models but that's more of a wishlist sort of deal.
