Zombies Swarm - Suggestions.

I used to play swarm server in past and as I remember Pumpkins were strong as they are here & only S.admins can use pumpkins. So if someone is paying for something then it must be worth paying. I don't think there is any problem with pumpkin

What chance i can have vs you? Do u think is balanced? 1 Pumpkin can kill the strong zombie in server (tank), that must to be reduce. The people can pay again and can have another extras...
