This is the only part of the book that I really dislike, and I really hope that as a gaming community we can fix this. The book is worded right now that units can see what the miniature would be able to see from their eye point of view. Why couldn't they have just said, infanty blocks infantry, monsterous infantry and monsterous beasts can be seen over infantry but block each other, and monsters can bee seen by everyone and are only blocked by other monsters. And we can say that hills that elevate you make you one size category larger or something. Why is that so hard for games workshop to do? lol
