Monday Night Combat Wiki

hi ive noticed something 3 times in my mnc career it is that some guy that i try to kill when i have juice on and he dosent and he isnt over healed AND he isnt an tank or with a gold armor it takes me almost longer to kill than i didnt have juice? i try to kill them with the tank flamethrower (yes i forgot the name and too lazy too check plz dont flame me or mention it) so yeah is it a glitch or hacks or something like that?
