How Is Built To Last better? You may get few more uses out of an item but Streetwise also affects nearby Survivors, I'll take Streetwise over Built To Last imo. The rest you kinda explained things I didn't know, and glad you explained, and things I understand. But outside of SWF, people don't have to unhook Survivors, and unfortunately not all the time do they unhook them.
This...this actually hurt me to read in so many ways
Then don’t read???
Strictly speaking unhooking isn't required. However the consequences of not unhooking are great enough that it may as well be, since if Survivors die on 1 hook then the remaining Survivors won't be able to complete the gens in time against a Killer that is at least somewhat decent.
As for built to last it's just math. Built to last is 50% while Streetwise is 25%. The advantage of Streetwise is that it effects your team yes, but that would require Survivors to be grouped up while using their items, which isn't super common, certainly not common enough to be worth 25% less effectiveness in solo que.
Remember, you'd need to have yourself and 1 other Survivor fully deplete their item while under the effects of streetwise to match the effectiveness of using built to last with no coordination required. A 3rd Survivor is required to actually surpass it.
Now SWF is a different story, which I explicitly stated. Since players on VC can deliberately group up to optimize efficiency as desired to get a ton of value out of the perk. Even then however I'd still see SWF using built to last often instead simply so that they don't have to group up and can instead split up for optimal gen rushing.
Nice. That could be insane builds.
Probably not. It has diminishing returns with most items.
