I think the banner is not exactly like crucible. There does seem a slight bit of difference. I play crucible and can do fine. Manage a 2.0+ k/d from time to time while sacrificing for objective but when I play banner there are times I just get crapped on by exotics which is understandable since they are exotics. But I don't think all the weapons and armor abilities are activated in crucible but are activated on banner. Maybe it's just coincidence but I've never had anyone with suros for example heal while shooting me in crucible but it's the bane of my existence in banner. The gun legitimately does more damage at the second half of the mag. I mean I agree that it isn't the low level crushing machine it should be because I'm a level 23 and don't get squashed by 30s but I think their still is a slight difference and it's the weapons. I've never experience it in crucible. I could be completely wrong though. But the problems I've had in banner i don't have in crucible.
