Plz try and not be as sarcastic as possible to elevate yourself or something. Anyway, i have fought vs jackhammers loads of times in beta and from people who have looted them. Yes it is a bitch but just as much as a chaingun. I try and loot chainguns so i have chaingun and jackhammer. So i use both alot and i can safely say they both have their place like all the weapons.
