So there is alot of discourse right now over PVP and one of the prominent tropes is that the game is too easy. Despite being a non-PVPer solo Hermit, i actually agree with this point.
But I don't think we should rely solely on PVP for the gritty survival and most of my deaths back in W7 and W8 were not from players but were instead from animals. In those days if a Bear aggro'd on you, then you were truly fucked. Let's bring back danger in Hunting.
Make it so that if an animal cannot path to you it automatically becomes invulnerable and unkillable. Make it so that a fight must be started with a path available to the animal in order for damage to be possible. Likewise if the animal loses the ability to path to the hearthling it will become invulnerable again until the hearthling is pathable again for 3 seconds.
Bows: obviously this will hurt the already weak bows since you will be forced to fight in melee, so to not kill bow hunting, make it so a animal with an arrow in it will be significantly slowed when running away (not when attacking) so that if bow hunters make a animal flee they can chase and kill it but if they misjudge their damage they get K.O.ed or worse for it (this would add an element of skill expression to bow hunting too) Also buff bow damage if this system gets put in place.
Alternative to the invulnerable solution is just make the animals run away. My only issue is if there path gets interrupted while chasing they might just runaway which would be annoying while melee hunting.
