Ok then what is problem happening is that now that the server no longer lags shots actually are registering and thus zombies need more health. Considering that registration should have improved by about 50% I suggest we try an increase of 15% health on all zombies and slight reductions in knockback for those that have values to support it. Also some changes to health regeneration rates to the tune of 15%-25%.
If the hit detection is 50% up shouldnt the knockback be GREATY reduced?
Health would help but thats not the issue.
