I don't get why people are complaining about this, I've seen people say in this thread I used to be able to survive every wave on suicidal with the bezerker perk before the update, I believe that suicidal is meant to be a challenge? Doesn't that help you understand WHY some of the overpowered weapons like the katana and the chainsaw were made so that players had to have more skill to be effective with them in the update?
I agree that suicidal shouldn't be possible for just anyone to beat, but the problem is that the weapons are totally out of balance with each other now, apparently.
