Not to say you can't train in Buried and not to say there haven't been fun camping locations like Firebaze Z the office, the motel in liberty falls, and of course the catwalk on The Giant but that's a remake.
I feel like this was the last map where camping was objectively a better option to training and that was also full of really fun camping locations like here on the roof of the bank or in the jugg alleyway.
