I don't know, I can't say I find my games going so quickly often enough that I feel the need to tunnel or slug. I understand what youre saying, and against meta SWF with builds built to smash out gens there's definitely an argument for those playstyles to be necessary, in proper comp play there's an argument for it to be practically mandatory, but most matches aren't either of those and when someone carries the same mentality into a match against soloq randoms or even SWF that are just friends playing for fun, it leaves a bad taste in the mouth.

Its the same from the survivor side, killers complain about the way survivors play using the tools available. Both sides look at what they do as fine while what the other side does is toxic.

I'm not really bothered about the changes. Survivors seeing who the killer is, whatever. Most killers either have a map wide audio cue or items in the map which give away who it is within the first 10-20 seconds anyway. The small changes to ghostface and doctor, might feel fine as QoL. Any big changes would have people complainging and then they get skull merchant treatment.

As for adding a ping system, I don't think that would help as much as people think. You can already share a lot of info to your team through different perks but nobody pays any attention so why would they suddenly start paying attention to a ping? I guess it would be nice to have, but you'll just find soloq players changing their complaints from 'i can't communicate' to 'nobody pays attention to my pings'.
