During the expansion reveal or in subsequent articles, they said shadowlands were going into Chromie Time and BFA will still be the new player experience after Exile’s Reach.
Chromie Time aint going anywhere, instead you can Chromie Time from 10-60 and skip Shadowlands altogether, which i am all for at this point.
new accounts that dont have a previous 50, or 60 will be forced to play bfa content, everyone else will have option to chromie time 10-60 and there fore skip shadowlands if they choose to.
