Seems silly to have to interact with some book just to view your trophies especially since it would mean teleporting to that plane. I'd prefer it like how it was in the first game if it returns at all.
Yes indeed, it was very easily accessible..
Take the formula from D1 and add also some snarky comments about how many skeletons you have killed (for example, when you near skeletons scatter in fear of their...life ,since you took so many of their brethren)
