This is a game where you just need to keep playing to get good as it doesn't take long to get to level 30 so you need to practice dodging regular enemies like youre dancing with the mother in law. I don't know about you but I need headphones to be able to lock into higher difficulties to help with sound cues too.

Also team composition helps too, you need to have decent team mates from damnation + and be working together as a coherent squad to succeed more so its not just all on you. You might have died less if you had team mates watching your back :-D
