Guild Wars 2

When a ranger pet is put away, taking fall damage makes it come out. Obviously, the idea here is that when something attacks you, and thus damages you, your pet comes out. I don’t think that a pet is going to do a whole to stop gravity, though.

I don’t want my pet to appear automatically at all. Please make it possible.

When my guardian falls, he forms a Symbol of Protection. Unfortunately, this really upsets any neutral creatures below.
I suppose it’s a little more realistic, considering how few animals in the real world would appreciate being fallen upon, but I think their usual reaction is more of a “shriek and run away” kind of thing.
For that matter, most of them would probably respond that way when you shoot at them or whack them with maces, but in Guild Wars 2, they take the offensive and try to eat you instead. But that’s not related to falling damage, so I might just put that in another thread.
