My list of current concerns in DBD
when killer insta DC at game start, we lose PIP and offering (screenshots), we shouldn't this is BS
people bring their low rank friends in games, lobby should not accept starting a game with a high difference in rank. We have a 'ranking' system in place, which at least could sort inexperienced people from highly experienced people. When a rank 2 player invites his rank 19 friends in a game, I don't know the magic behind but they'll come to my game (rank 10), the match making is then ######### for everyone, killer AND players. Killer because the experienced player will ######### on him easily the whole game, and players because the low rank friends will do the most stupid things all the time, when they'll not simply do nothing hiding in a corner or all kind of idiotic things like that. I think the maximum difference in rank should be 5 ranks max from one end to the other in the lobby. Or else simply remove ranks altogether and just say we don't care about balance, fun, or anything at all for the game. I actually think in this case the higher rank of SWF should be used for matchmaking. It would at least prevent the 'exploit' for higher rank players to play in low rank lobbies and ruin the killer and survivor experience.
OR one good idea would be to have two systems, a SWF mode, and a solo mode, then killer can have option to refuse SWF in matchmaking games. That would help lot of 'balance issues' regarding communication being way too helpful (I admit I sometimes play with friend and abuse that on TeamSpeak), and removing the fear of not knowing everything that is happening on the map.
deranking. too much people derank on purpose and this is the same as having a SWF rank 2 + rank19, it breaks the ranked match making and eventually kills the fun on both sides. You anti deranking system does not work at all. I also see way too much streamers deranking on purpose, live, like it's OK no problem...
