Yep, it's almost like it has an organic difficulty like I said at the very beginning when people were complaining
Some classes have it a bit easier the first week or two, but once you get some of the upgrades (the dps ones especially) you're SO golden, those withered just do way too much damage to ever be in danger. Even as a 'good' class, I evolevd from week one slowly walking through as blood, to now staying frost and literally just running from room to room and hitting 'berserk' while I loot boxes and my homeboys kill it all.
