Changelings, and why they're just too damn powerful

I agree, changelings are just monstrously overpowered and it has become far too common for one to eat the near entirety of the crew.

The acid spit should be just that: acid that you spit at someone and it burns their face off or something.

It should not knock you out because that's what the neurotoxin sting is for.
