Keep in mind Act 1 is still missing one third of its map's area, the goblin forest still hasn't been added yet I believe.One thing I noticed playing the last update:
The map doesn't seem to offer enough content right now to keep up with the stuff happening in the castle.
There is no balance between both parts, I'm in week 36 now and there is nothing left to do on the map besides running around and hoping for chance encounters.
I think that's not a new problem, but it seems to have gotten worse.
It is true that if you optimize your movement you can go through most noteworthy locations before the timed events start getting in the way, but I personally don't think that's a bad thing. Devs probably wanted most noteworthy locations to be possible to visit in a blind playthrough, if you are optimizing your movement you can use your extra time to track random events like you mentioned.
