Any MMO was bound to have job classes that came with their own unique characteristics, and from there a curious phenomenon would appear: Players from different job classes would habitually voice out the weaknesses of their own job classes and which aspect of their kit was trash. However, this would only be something only players that had picked the same job class could bemoan. For example, Archers would often complain about how helpless they were in close combat, but if a Fighter were to mention how he could easily trounce an Archer, this person would succumb under the harried refutations from the Archers, raising hundreds of different scenarios where the Fighter would be taken down instead.
This situation was quite like how a child would not allow any outsider to insult their own household. From Gu Fei and other martial practitioners' perspective, this was akin to being prejudiced against people from another sect.
