Now that everyone has some time to have experienced the fat grey terror known as walrii I'd like to make some observations of my own.
Their movement speed:While I agree that you should have zero chance of escaping a walrus on open water, I really feel that them moving faster than you possibly can on dry land is a bit insane. As it currently is, if you aren't equipped to solo a walrus and it aggroes you there is almost nothing you can do (aside from going in a cave/house) to escape it. If it was possible to outrun it like a boar on land I'd feel they would be substantially better balanced.
That they flee:It's a bit irritating having to block them in completely while being attacked to be able to kill them, yes they bleed out eventually but since they have such a high hp pool and move so fast it's nearly impossible to find the corpse. Which I suspect is also destroyed if they bleed out in deep water. Of course, if they did get slowed on land then them fleeing would not be an issue at all, you'd just have to drive them to shore to kill them.
Otherwise they are a great addition to the game Jorb and Loftar! Keep this sort of thing up, new animals that have new tricks is awesome!
