Why are Styptic Agents still a thing

Not so easy many survivors use it behind corners and you cant notice it, 5 seconds is most times enough time to get to some loop and its still best addon on survivor side then syrange is second. Styptic just hives you few seconds against blight,nurse and is worthless against ghoul but m1 killers get destroyed by it and now Im seeing full lobbyes of styptic especialy on swf teams and its pain to deal with it the just add dead hard and ds and that survivor has 2-4 pontencial more rounds looping you then he would have normaly.

You mixing it up and making it more complex than it is exposed and endurance are both tools that help each side to progress their objective and slowdown other sides objective. Endurence is in survivors favor it wont get you downed when the killer should down you and help you by buying you and yours teammates precius time you both need to make progress in your objective and slow killers objective, same goes for your m1 reduction cooldown and loop resources (paletts and walls) which help survivor too but they arent as specific as endurance effect same goes for exposed effect its something that comes in specific situations or is created by specific powers,perks,addons its not common as paletts. Exposed effect just makes killers chase time shorter, saving his precious time and helps him progress the game and his objective to create preasure on survivors snd killing them faster then he would with m1 (taking just one health state).

Bloodlust isnt more fitting its just speedboost and endurance is having one health state more and exposed is just dealing one health state more damage than just m1 or simular attack that just deals one health state damage so they are more connected then the other things like bloodlust or m1 cooldown you mentioned.

Just so I'm clear, you think the outcome of being on the ground, unable to do anything for a survivor player is the same as the outcome of having to chase the survivor a little longer and hit them again for the killer?

Being on the ground isnt good but then it depends if the killer pick you up and goes to hook or leves you there because the slugging part feels bad thats true. But in the core getting fast down or extending chase for tens of seconds its quite closer than you think because killer is occupied and others can do gens and other things which they normaly some of them couldnt if the killer was on them and someone had to go pick up slugged survivor or unhook him thats reducing preasure caused by killer and it makes huge difference on gen progress.

Flat out ending a chase on hit is the same as extending a chase on hit?

It can be because one hit down is huge amonth of time saved and same goes for extending chase for survivor with some endurence which helps you reach other loop or safe location with resources and keep killer occupied for longer. Tell me isnt it noticible when chase that would last 40 seconds will last just 20? Personaly I think it makes difference 20 seconds is just little over 1/5 of the gen and 40 is near 50% of the gen which is huge difference plus if killer has hook far, just for fun fact pain res damage to gen is 18 seconds of time I think.

Do you think shortening and ending feel the same for the players involved?

Look no offence but feeling and facts are two different things if you die then it feels bad as survivor but if you die and your 3 other teammates escape even if it feels bad for you your team and you (because you are part of that team arent you) won that match in terms of kill rate which is something that is based on winning and loosing if devs are balancing game around it to be in some range which is now 60% kill rate. So it feels different but the effect is same for each side one (killer) creates preasure on survivors by having slug or hook (mostly hook) which pulls one from 4 surivors for rescue and other is found and chased and one is left with "free hands" and can do gens or what he wants thats preasure on survivor team, if survivors extends that chase by other 30 seconds or 20 thats time these two out of 3 survivor have "free hands" and can do gens or heal whatever they want so I see it kinda same as impact that is deciding the outcome of that match but feeling its different so lets get these two things clear.

I'm not arguing for or against either mechanic - I'm just saying they aren't the opposite of each other when you consider the outcome having them in play produces.

I see them more as opposite of each other than other things as increased gen speed and gen regression, they bot (endurance and exposed) kinda do opposite of each other, exposed makes killers chase shorter or none if he gets instadown on unsuspecting survivor (like ghostface ambush or billy snipes someone while moving around the map) and endurance gives survivor "another chance" and buys him more time to loop killer if he wants to chase him like dead hard or otr, styptic they all give survivor another run (sprintburst from getting hit is like 18 meters in straignt line but actualy more because killer is slowed by some cooldown from attack in most cases) which buys him more time in the trial and his teammates to do objective or other things.

From my personal experience, I am cautious and comparatively paranoid when exposed as a survivor and as a killer I'm maybe a little annoyed but otherwise couldn't give a crap if someone has endurance. That doesn't strike me as equally powerful or impactful opposite effects operating in the same space. It certainly doesn't strike me as usable in a 'imagine if the other side had…' argument the OP is making.

Im more cautious when Im exposed ot killer has some instadown too because i dont want to be downed super fast, but Im paranoid for styptic or dead hard too because not all killers can just take that hit and ignore it and try to bait it or wait it out killers like blight,ghoul,billy,larry,krasue,dracula dont care that much if you hit your dead hard because they have strong power and can down you way faster then m1 killers or weaker killers like wraith,trapper,ghostface,doctor,clown,freddy which most of them have no mobility strong to catch up that fast or theirs antiloop isnt in their power with that mobility like stronger killer I mentioned above so it costs them that time and effort by just hittying that endurance effect on survivor which you kinda have to agree its logical you will care about dead hard with knight then with ghoul who can catch up in few seconds and get that another hit inles time with les effort then that knight.

Thats just my point of view and opinion.
