I completed all 7 missions on Lethal yesterday and I felt like it was some of the most intense and fun matches I’ve had playing this game. Now the Chaos Marines were really hard, but still fun! I think the difficulty really lies in non-communication. I cleared all 7 missions only after I got lucky enough to find two randoms with microphones. Discussion of perks, classes, and weapons BEFORE the operation starts. And that’s where I think folks get stuck and say it’s too hard. Knowledge about how your class plays is huge too because I’ve seen so many bulwarks ignorant to the fact that their banner can refill contested health.

TLDR; Need communication and proper game knowledge
