It melts my PS4.
I have to heal to contribute because the bosses never load in.
On PS4(not even an OG one) even TPing from one side of an area to another can take up to a full minute to load.
Not even TPing between areas, from the Ostal to Fort Jobb can take a minute to load.
Lately the hunt trains have been waiting a bit before shouting the coordinates of the mark, and it's been super helpful and they've been getting thanked like nuts.
If it weren't for the community being understanding this would be pretty impossible on console.
