I laughed when once on the podcast he was boasting how DbD does the rank system right. When, anyone who actually plays it, can tell you that the rank system is a god damn joke. Survivors can run in place and fart themselves and still rank up. Killers can rank down for doing too well. Not to mention the ranks are completely destroyed by SWF players. SWF means Survive With Friends where a group of survivors from 2-4 can play together and play in the same match. SWF completely destroys the balance because (1) these players will use Discord to communicate with each other when the game has no in-game voice chat or any kind chat and (2) what often happens is that several players could be rank 2 and one guy could be rank 18 and they get matched to a newbie killer around rank 18.
Saying DbD has a good rank system is asinine and even the most ardent of white knights for the game and the devs will admit to that.
