I read that you added damage multiplier in a previous post but i have the opposite problem to that post, i have mods that give alot of weapons and also mods that add alot more, and alot harder enemies, and i have those on x10 multiplier to balance everything.
I have the Fulgorian damage multiplier on x4 so they actually hurt quite alot, but their HP even at 500% evolution is not much compared to my arsenal.
