PvP 2x2 how to organize? (Dark Souls 3)

Vadser
If, for example, a player will run with a fountain and 2 dark spirits or guards will burst into the world, but this is basically random, I somehow ended up in a world where there was a whole crowd of both dark and white and guards haa the batch was notable

called a friend on a white sign. called two guys on the red sign. mission complete

Duzmond
well, this is understandable, I wonder if it is possible to arrange something on purpose

Vadser
run along the lock where the dogs appear, you can gather a crowd against yourself) well, or as mentioned above, use the red call signs

how did you end up in the so-called fight club where they fight in a tournament style in a circle, can someone advise where and how people gather like that?
