first. change the time of the fire nade its not can be so long its need to be like 4-7 sec not more .
and then the zm evolution have too much hp i mean when u die like 5 times you have like 5 k + and you can kill someoen with sb like nothing
and i have just something elso change the maps its alwyas the same maps and its will be good if u will do like that the map will chnage in like 20 minuts and not with 7 rounds
i play for like 8 years in ZM mode and i never see somethig like nade more then 4-7 sec or zombie with more then 4 k so i hope you will maybe listen to half of my stuff to have better server and to enjoy more
