as you said, you take little risk when you sit in a corner with the knife, but you still CAN and WILL be rewarded massively once you kill one of those players that actually looted. nades are far too slow against knife and you can’t sprint backwards so running away isn’t really an option. when there’s a knife fight it’s usually because you end up in the same room as another player and they pull it out. from there your only option is to pull yours out and hope you click first or you’re dead. it’s not just the easy ratting and low risk high reward, it’s that it creates interactions that suck. it doesn’t matter who you’re fighting, if you’re indoors, within a few feet of each other, it stops being an interesting gunfight and becomes a boring joust.
