The lower difficulties are way to hard right now, i think mainly the health + damage of the small raptors and drones mixed with the groups that were recently added is the culprit. Plus i'd like the smallens to go down relatively quickly even on higher difficulties.
My thoughts are to revert the heath and maybe decrease the damage just of the small enemies as i quite like where the big ones are at right now but there are other ways this could be rebalanced (you devs are awesome im sure you'll get it good :) )
unfortunately my editing software is on the fritz so i cant upload a clip right now.
