[Suggestion: Normal Zombies able to climb the walls!]

What do you guys think about adding "climbing the walls" ability to "Normal Zombies"

 

Let's face it, these zombies aren't dangerous at all (in comparison to "Tough Zombies", "Special Infected" or even "Animal Zombies"). If "Normal Zombies" had the ability to climb the walls it would be freaking awesome (even if you gave them this ability only for bloodmoons), they'd stop being a total waste of AI slots, it would deepen the gameplay and it would (to some extent) solve the "pathing" problem for some zombies).

 

This way it would be a bit harder to cheese the game but at the same time those zombies would remain quite weak.
