By that I mean my weapons are extremly strong most of the game so I am doing a lot of damage but on the other hand so is the enemy.
I agree. I have thought the same several times. This makes the game seem too easy many times and too hard others. More too easy than too hard, but still. It is strange to slaughter enemies in seconds and those same enemies suddenly kill you in 2 seconds.
I think less damage on both sides or more resistance/hp on both sides would make it more balanced.
This is nor the first game where I have thought this tho.
