Your talking about 3 different things so I’m confused. Express pass doesn’t do anything but help honing rates. Power pass is gifted free to us probably once per 2 months and 2 classes released. Knowledge transfers are from your stronghold and cost gold. What are you asking?
By express pass, you meant express event? Since there’s no such thing as “express pass.” We won’t be getting a new one when Valtan drops because the current one is still in progress.
We won’t be getting a new powerpass either. If you already used up all your 3 passes, tough luck.
