Why developers support toxic gameplay?

I swear, any post involving anecdotes of killers being gracious, fair, or human beings as opposed to evil lizard people is literally invisible to you.

Power-tripping players exist on both sides. If you played killer at all, you would understand that a.) some killers are perfectly chill and b.) some survivors are horrific sweats whose goal in the game is to tilt the killer as much as possible. Assuming one side are casual innocents and one side is nasty and evil... really blatantly lacks perspective and is a profoundly unhealthy viewpoint besides. Earlier today you said that the purpose of the killer role is to ruin the game for survivors, but this game would look pretty damn boring without a killer - unless games with AFK killers are your favorites?

I personally enjoy playing killer more than survivor because I have the power to make the game fun for everyone. I can give good chases, spread out my hooks, and then chill out at the end, and reap the rewards of a happy team. I'll get ######### on occasionally by a strong team, or profoundly BMed by a nasty one, but if you're frustrated with the inability to control the flow of the match as survivor, you should really give killer a try. Be the change you want to see and all that. (And maybe, while you're at it, realize that playing killer by the survivor rulebook is not nearly as effortless as you preach it is.)

To the OP, I don't entirely agree on some issues raised - I don't really think camping, tunneling, and slugging are toxic by themselves, only in context (facecamping at 5 gens is scummy, tunneling at 2 gens left isn't), and I'm alright with the devs' stance that they're allowed, just not winning strategies on their own, and letting that be the discouragement. But I totally agree that they've exacerbated issues unnecessarily by creating incentives to do these things. Survivors needing to escape with the crowns is incredibly obnoxious on solo queue, doubly so when games are full of survivors that are just running around looking for crowns instead of doing gens. I'm finding myself way more frustrated playing survivor than usual because I typically didn't care about escaping, only playing well - and now everything hinges on escaping and I'm getting mad over games I wouldn't have cared about before. And tome challenges are full of challenges telling killers to slug for the 4k, or set up always-popular basement builds, or bring NOED and afk all game, and telling survivors to throw the match by performing an action with an obscure perk, or hiding next to the killer for a minute, or getting 4 unhooks in one game, or pointing at the killer while they're running towards you. There isn't enough time in a match for survivors to screw around, which rifts encourage, and players will happily throw each other under the bus if it means getting their rift challenge done.

(And then there's the Myers achievement, which tells the killer to go create the most boring game possible, for as many times as it takes until it works and nobody rage-DCs at the last second.)

I'm cool with giving bonus points to killers for not tunneling or camping... I assume that the check wants it so that survivors aren't hooked consecutively/the killer didn't trigger the 'proximity to hooked survivor' score event. But that's as far as I'll go. The problem with making it impossible to tunnel or camp, beyond the scenario where the killer has to do one of those things to salvage the game, is that skilled survivors will abuse it. You saw this with old DS; survivors that have protection will use it offensively and block the killer from going after other players.
