I haven't been on the game long, but I heard a lot of people say it was more favourable to survivors before and the updates just made things fairer for killers.

I just wanted to know if anyone had any evidence for that, because I can't see anything and actually found something which looks like the opposite. Look at the link https://progameguides.com/dead-by-daylight/latest-kill-stats-popularity-of-each-killer-in-dead-by-daylight/

It says that the kill rates for almost every killer were above 50%. Doesn't that mean that kill rates were always higher than 50%? So why was the game changed to make kill rates higher?
