Now I don't know exactly how stamina works vs costitution, etc... so i'm only suggesting to consider this thing:
Animals aggro should be even more common and in general all the danger from the wilderness to bring more excitement....at the same time this could be balanced with more ways to escape that danger.....so consider to overhaul like stamina works, maybe a bit less drain on grasslands, 4th speed even on forest biome but with a huge stamina drain that allow you to sprint only for very short distances....same thing with animals, they already have some speed buff when fleeing, etc.. for what i have understood, give them also, based on the type of animal, some way to sprint a bit initially but you can outrun in the long period, others instead you can sprint away initially but then they will catch you in the long run....etc...to differentiate a bit.
I know, probably this thing it's very hard to balance well....but could be a lot of fun.
In short, dangerous animals and enviroment & more ways to counter that danger also....so that player choices would be more relevant..... = lot of fun
