I find it really annoying how if you aggro a zombie and a bunch chain with him, you're basically screwed. You can run to the end of the Earth and they'll still be chasing you. Most people would just quit the game or disconnect instead of let themselves die. The player needs more options when it comes to getting away so please make it easier for zombies to lose sight of you or that after a time they don't want to chase you. It's just not very fun currently.
