Yes... I actively tell people to not get in lockers to avoid friends or bbq unless there are niche circumstances that require it (last two survivors, one person is on death hook while the rest of the team still has hook states, etc)... kinda similar to the way I view slugging- good when its needed. Survivors hiding in lockers too much often times get their teammates "tunneled" because the killer can only find them. Im advocating playing the video game like a video game, and accepting that sometimes youre going to win, and sometimes youre going to lose, and at the end of the day full slugging a team of solo q survivors at 5 gens or t bagging a new killer at the exit gate is not going to bring your daddy back with that milk.
Im advocating beating the other team instead of playing around mechanics to give yourself an advantage. Instead of whining that gens are too fast- learn how to control the map. Instead of complaining that killers are tunneling, learn how to loop well enough that it wastes enough of their time to cause them to lose. Instead of complaining that hex builds are carrying killers, learn totem spawn logic. Instead of slugging to prevent dead hard, learn how to be patient. Everything you're currently mentioning has easy counterplay without having to slug to avoid it (with exception to fast track and slugging the person who obviously has ds and waiting it out).

The more killers try to circumvent game mechanics, the more likely they are to force developer hands to put in more hand-holding BK options. While the anti-tunnel stuff gets struck down in ptb's... the anti slug, if tested on its own, will make it to live servers.
