Here are some suggestions i want to place, i dont know if these changes are possble tho
Permanent Unlimited Ammo should be removed from the server instead players would have to buy them (To increase difficulty and challenge)
Nemesis HP should be lower to about 70k (Armagaddon Mode is totally unbalanced with 100% fatality rate for humans.. unless the round is finished)
Double jump should be removed since there are jetpacks however players can buy double jump through ammo packs
Tags should be removed, for admins they will get a default tag for admins which will be [ADMIN] with exception of HIGH RANK ADMINS
Server boosters should receive perks like green text message or green highlighted name when they use chat, Special VIP skin (other than smith), Double jump, custom tags. Of course these are too many perks for server booster, to solve this, players will have to boost the server seperately for each perk. They can specify what perk they want when they boost the server. 1 boost for 1 perk.
Additionally donaters can receive perks like free survivor or sniper after 24 or 48 hours, custom tag, free 100 or 200 armor, free 30 packs per 10 min, green text message or green highlighted name when they use chat, different zombie skin, etc
LM health should be decreased from 800 to whatever you think is better
I don't know if it possible but if it is possible then please add more extra items in the server
Thank you for taking out the time reading this topic,
This is only my opinion, i hope the management does what i thinks is best for the future prospect of the server itself.
