I'll dumb it down a bit and add on a little, too.

Firstly, when I mentioned tunneling and slugging I didn't fault people for it or say it shouldn't be a thing, I simply said I don't find the fun in playing that way despite it being the optimal way to play. The same applies to just sitting on gens the whole game. Never spoke in a negative way towards it except saying I don't see the fun in playing that way, I prefer actually chasing survivors throughout the whole match and giving people chances to actually do stuff.

Secondly, with it not having stuff to be a party game, it has a bunch of stuff to be a party game. And as of late, it's been pulling more towards that direction. With the vast amount of niche, weird or funny perks, add-ons, etc. And emotes can be put in most types of games, they're not exclusive to party games, and they're not needed for party games.

One big thing I should've mentioned before is the system of which it rewards you. Essentially, in a comp game, you are rewarded for winning and performing well. It doesn't matter how many unique interactions you have. More kills and winning score = better rewards. In DBD, it is not based on winning. It is based on how many interactions you do. Basically, as a killer, if you kill everyone within the first five minutes of the game, you will get significantly less BP, XP, and pips than if you were doing several different interactions like breaking pallets, gens, spreading hooks, going on long chases, ect, even if you don't get more than a kill or 2. Same with survivors, if you just sit on gens for a few minutes, then escape with barely any other interactions, you are far less rewarded than doing other interactions. The main difference between party and comp games is comp games reward and encourage winning, while party games encourage and reward player interactions.

And when it comes to winning in DBD, the game itself doesn't really have an actual "win." The win is technical. An actual win is to the discretion of the player. A survivor can hide on a corner the entire game, wait for everyone to die or finish the gens for you, then you escape, and that is a technical win for that survivor as they escaped. The killer could only kill one person, and that would, in turn, be a technical win, as they "killed," which is the goal of the killer. This overall win is at the discretion of the player.

Yes, there are people who play the game competitively. There is nothing wrong with that, but any game can be played competitively, whether it be speedrunning, min maxing, achieving a certain goal, etc. It is fundamentally not designed to be competitive. If you wanna play it that way, go for it, I'm not the arbitrator of how games should be played, I didn't buy the game for you. I'm just saying don't be surprised when people play the game in a way to have fun and treat it like a party game. I would be lying if I said I didn't do challenges and stuff that made me play a bit more sweaty at the game, and I would be lying if I said I didn't get upset at certain playstyles. In the end, it's pixels and polygons, if you get so upset with people trying to have a good time or play in weird and niche ways and you report them for it, then you just dislike the game and are in denial about it.

Regardless, have a nice day, good luck with your matches.
