THX for pointing that out, I think I have considered that too superficial

You could just double the pollution to get the desired effect IMHO

i would suggest to let everyone play their own way, why should someone have a problem with it when i decide to use turret creep? it is my savegame, not yours, if you dont like it just dont use it ^^ turret creep is not a problem, just add more ways to fight and the players will find their playstyle ...
