I think the update that made creature walk around when no player is there is good. Makes the game more realistic.
But there's a thing i don't think is good or should be changed:
example:
When you are at a place where agro creature come in different sizes, and you need only 1 type of them. If you wait there, the wrong types will walk away to area's where other people walk. Those people don't want to face those, cause might be strong creatures that kill them easily.
My suggestion is to a limit to where creatures can walk. Like 4 steps from where the came from.
