A Fix For DC'ing During A Match
Give them a time-out timer for 30 minutes each time. Make it stack so after 10 DC's in less than a week, it doubles to an hour. I'm telling you right now, you get enough time-outs and you'll think real fast about DC'ing. They do it in Overwatch and in CS:GO, why not in DBD? You want it to be competitive, you want people to stop DC'ing because of saltiness? Give them a reason to finish the match or take a 30 minute break instantly to help with it.
