Why does everyone use PF as a representation of the game?

[SeiyaSoiya]

I mean, the weaker jobs are being excluded for the top tier statics as well and have the lowest number of clears on the log website. I wouldn't say PF is a "representation" of the game, but the large majority of people doing end game are pugging them through PF. Hardcore/midcore statics are the minority.

that's not true, week 1, day 1 and world first statics had MCH RDM RPR PLD and WAR in them
