What improvements would you like to see in the environment?

[Canadane]

A few beasts that run away in fear when my character goes close by, starts aggro when attacked.

I recall 1.0 had something like this. Sight aggro worked differently depending on the mob type.
Timid mobs would run away unless you actually started fighting them. Curious ones would come up to you but only to check you out, maybe sniff you lol. They wouldn't attack unless you did. And aggressive ones would just start beating you up.

I do miss things like that, removed for the sake of simplicity.
