Here is how I see it: If you were in this world in real life, would you not use everything you could to survive, every imaginable way to trick the walking dead and keep from being eaten? Would anyone in the Walking Dead say, "well that is a bit unfair to the walkers, I should make it easier for them", not likely.
The game is a survival game, that means survive, not trying to be fair to the enemy trying to eat you, just survive some way some how. I do not even see the idea of avoiding them on horde night cheating, you just outsmarted the enemy in the game, good job. I guess the enemy would be the fun pimps programming, but outsmarting the enemy in any way in a survival game without using god mode or cheats is still winning IMO.
