General roasterrock the pinnacle of humans has been getting slammed lately by defense breaker trait the moment he emerges, while it is true that the general can require skill to stay alive but once you get hit by a zombie with a defense breaker you might say it is over, if you don't die your armor will be almost gone within few seconds. So I have but two small things that I want to suggest that I think would make him better.
Non-boss zombies can't debuff the general with defense breaker. That means only when you are not a boss you can't use defense breaker on him.
Add vaccination. Cannot be blinded by poison
Zombies have proven to be strong and competent lately, so such an buff will not be too much of a hassle for them I believe
