Colorless said:Demo have it easier with hordes of enemies at higher difficulties they're not suppose to handle enemies like scrakes nor FP and i think you're suppose to kill a siren before they scream.Not to mention Firebugs have a bad time killing scrakes and FP's too.
The Demo perk was pretty much tailor made for killing Fleshpounds since they're weak against explosives. It can handle Scrakes if need be too:

Firebugs can handle a Scrake pretty easily with the Husk Fireball Launcher. All it takes is two fully charged headshots.
