I dislike the change that some journey chapter are locked if the previous chapters aren't yet completed. This is because I liked to complete a journey, but don't always have the time to complete what it throws at me.
Agreed. I liked the flexibility of choosing what I wanted to do, while still making progress on the journeys. Now, if I want to do switching on Cajon Pass, I have to choose between spending a bunch of time in the ES44C4 first, or having the switching not count toward the journey, and having to redo the switching services later on.
As mentioned in the earlier report of this, it prevents you skipping past any bugged scenarios or runs.
This will be annoying on some like Arosa. There's an entire chapter that does the turnarounds (I think it should have been mixed up more with services).
