What should I do in a situation like this?
rank 1 SWF, all players with a few thousand hours in dbd
VS.
rank 7 ME with 370 hours in dbd (plays surv mostly)
my braincells were literally burning after this match-
pls rework your matchmaking system ASAP, its horrible.

Try your best and find whats fun to you or you'll burn out quickly.
ok, but how should I have fun when I get full swf and I cant do my quests? They're tryhard, toxic and lobby dodging is eating up all my time
Thats up to you to discover, for me it was accepting many losses but maining Oni with Brutal Strength, Fire Up, Enduring and Spirit Fury for a few months because it was fun.
When it happens, try to learn how they play. Playing against much more experienced players can be a great learning experience.
push through my dude, dudette? playing killer is a great experience that helps you play the other side better, vice versa, and facing a swf helps you deal with them in the future, it painful and awful i know, but it will help in the long run
