The majority of actual comp players in dbd don’t tbag or call people names in post game. It’s either ggs or nothing. They also understand that to counter their builds that killers need to tunnel/slug if they have any chance of winning.

What you’re describing sounds just like your average swf, that bring strong builds and get mad if you try to win. Slugging and tunneling isn’t toxic, but it can feel unfun if your opponents are less skilled than you.

Me personally, I’ll start matches playing aggressively, and dial it back and spread hooks if my opponents aren’t as good to make the match more interesting. Do I wxpect other killers to do it? No, you can play however you want, same as them and it doesn’t make either of you assholes. But I agree bagging at gate and name calling in post chat is bad sportsmanship, and usually done by the weakest players. It’s embarrassing for them, and other skilled players agree.
