There is why I think those two servers should be kept separated.
To get an opinion, I've searched servers who are in competition with ours, and ended up with only one :
The Walking Dead Craft Survival. Even if this one exist, he still lack in texture pack, details by dedicated staff and fans, and in graphic. Others zombie survival servers or games are different enough not to be similar.
What TMD game offer :
a) 100% customized environment; even the tree are all handmade
b) Who help to create this insane devastated and so detailed atmosphere
c) Who open room for RP by offering more than 40 kits, to be played
d) Where players could create community, start wars and experience every scene see on TV
e) Exploring, looting, hunting, scavenging are just a few of the reason to play
f) Right scaled buildings and vehicle that you almost could all interact with
g) His own shooters systems
Why do I disagree with including pain without cooldown
a) It remove realism and negate RP
Quote : A Telltale Games series
Kirkman has said that, unlike typical zombie games such as Left 4 Dead, it focuses more on characterization, character development, and emotion than action.

b) There is less focus on survival and more on individual built up
Quote : The walking dead survival instinct
Supplies will be scarce and players will need to carefully manage rations, ammunition and supplies as they make their way through the game.

c) The abuse is just too heavy, as example when a players use high CPS, my computer get delay, then every single action become a pain.
d) If the only reason to merge those server is to benefit players who have invested real money, those kind of people would never be happy by anyway.
e) As said in the description, what could think any new players if he just kept been abused by overqualified players, then keep losing even after looting nice equipment because he din't know we could spam pain. Do you think this guy would like to came back?
f) Just try to answer the question : Who rule TWD world in the TV show and Comic?
i) The zombies
ii) Psycho like Negan and his crew
iii) Jugg players
g) Just talking about RP, If a players who have Titan rank would not like to randomly re-spawn with a characters kit, without access to his Vault in the first 5min, why would any VIP or new players would like it too?
h) Just check stats about players choice in Hell night. What is more commonly chosen as game type? Normal or legendary loot? I've read that some players would not like legendary loot because its too hard to fight back the lucky players equipped with golden barret or golden desert eagle.
I) So in a way to help staff to stabilize differences in the shooting systems. I vote to cut in abusive behaviors first.
So I don't say that I would never like to play a game where CPS is more important than strategy, if I upgrade to a better computer one day, but for the Sake of RP plays and competition, please keep separated the two battle systems! One for experimented players, and one for the new one, to leave them space to learn while having fun and to play a characters.
