Noticed two more things:

1. With selected priest, you can now tell a region's religion rating (your own religion). Good that it finally got implemented from M2TW

2. Anti-cavalry stake barriers (deployment) are now completely invisible. In fact, I was wondering why my infantry were climbing stuff in the midst of nowhere. I found out the hard way what it was when my general went over it a bit later.
I think its problematic that they are don't become visible even after you impale yourself or your infantry walk over it.
