My 1:15 run uses a slightly different route (the cryptowallet is in a different spot) but i don't know if there is actually a big difference between that route and your route. for the rest the route is probably maxxed out except for when someone finds a way to throw the bag in the objective from on top of the vent
I have tried both throwing in the bag from on top of the vent, and also throwing in the bag normally and then climbing up the vent, but both seem barely not possible. I have tried placing deployables to get myself more height so i could jump on the vent, but deployables have no hitboxes so this doesnt work. It would very very maybe be possible to throw the bag from the vent onto the ledge and have the bag bounce off the ledge into the objective, but it seems hard to do and even if its possible it would probably require a specific setup to get it to work. I'm still looking into it tho.
Preplanning favors as random drops doesn't make sense at all. I hope they change it later so we can just buy them.
Has anyone figured out how to get heist specific preplanning favors? They seem to randomly appear and disappear in the menu and they're very useful for getting faster times, so finding a consistent way to get them seems like a must.
