How did List camps work on blue?

[Ceion]

Just got done doing my Manastone (shit was the worst, never felt so sleep deprived) and while I was miserably sitting there for hours, I was wondering how this camp would have been on blue without /list? Was there a list people just kept themselves? Or did one guild just perma camped it?

Also brings another question, obviously with /lists in place I’m sure there is double the amount of Manastones than blue had already, would this essentially make Manastone too common that it completely devalues it?
