By the looks of it, the main problem is the game is too player-reliant, it doesnt seem zombie isnt that much of a big impact anymore. This may requires increasing the zombie count on servers. So heres my suggestion: Random urbanised towns are overtaken by zombies in different servers, these towns will have more loot if that place is overtaken. This will some how force a group of players to work together to clear the town (or a building) where big risk comes great reward. Zombies can be in buildings aswell if overtaken. This may reduce the amount of bandits aswell (as said before, it may require a small party to clear the area). You don't have to clear the whole town to get what you want. With that said, a few players cant handle a horde of zombies? by being tactical, it can. My next suggestion is zombie/corpse flesh repellent, where you can cut up a corpse and splat the flesh and blood on your clothing, zombies will ignore you if you walk near them, unless you sprint, they will get your attention. It will of course have a time duration on how long the flesh and blood stays on your clothes and by sprinting, you will drain off the flesh and blood faster. This can only be applied when you are out of combat (no zombies are chasing you), else the zombies will still chase you if you have the corpse flesh/blood on you. By putting this on, your moving speed can be reduced by a certain amount. Another suggestion is Weather. Sunny, rainy.etc, nuff said. Rain will also remove the corpse flesh repellent completely. My next suggestion: Luring zombies away, you can throw your tin cans or wateva at a location to lure zombies away, or kill someone to lure zombies to enemies who are hiding. Only works if you dont have zombie agro.
