This is one reason why I dislike that it's pretty annoying to gear up more than one class at a time. If you like MNK though, you can just use the gear for that, but you can't tell your preferred class will be crap and that people will dislike your class. Very rarely have i seen in other games that it's just outright OK to kick people based on their class and literally no other reason. Making a group isn't all that easy especially if you don't have many friends to help fill those roles. You may get lucky, but not always and would just be nice to join the already made groups, but since there's such a stigma on that, They need to address it by fixing their classes or getting rid of some meta/synergy stuff and just buff some of the classes.
