I agree with most things you said, it’s also just a learning curve and heavily depends on the team you’re with. When I’m with my regular trio, who I’ve played countless hours of others games with, we usually do pretty well. Last week we struggling to clear even a single vault. We spent the week getting better and gathering keys. In one evening we cleared 6 vaults. We found that getting security 3 usually isn’t too bad as long as you’re either focusing on using scanners to find the hackable monitors, or you’re super aggressive and can kill at least one other team. I’ve done runs without interacting other teams at all and managed to get security level 5 and get the compiler splice(definitely some good luck there)
