Let's say we are playing a map with a large body of water that a bunch of humans can swim in.
Now let's remove the humans except for one.
Now we have one human swimming around in the water with last humans benefits ( +100hp and x1.5 speed boost ).
It is almost impossible for a zombie to hit a human that is underwater because either the human is laggy or the server is, and if there is no lag, it is still difficult.
Zombies begin to get frustrated for trying to kill one human swimming around in the water for about 3 to 5 waves.
If anything, I request that last humans should get damaged (or killed) when submerged in any water. Even if they touch it.
This strays them away from using such a cheap strategy and can keep from killing the server all for just trying to kill one human.
I know this can be implemented (pl:IsSubmerged or something like that.)
Opinions?
