Although bandits are necessary to this game, there should be more emphasis on teaming up with survivors instead of the traditional KOS (Kill On Sight) attitude. The ratio of bandits to survivors is more than 50% in the bandit end. If the zombies were more dangerous (not glitched, able to hit while running, more dense in cities, and can spawn inland) and you could accomplish more things with a partner (make bigger fires, share body heat to avoid hypothermia, other player can make a splint for broken leg, another player can hoist you fireman style if broken legs to run from zombies, etc), then there would be less emphasis on being a bandit and more on just trying to survive or helping your mate out.
