Why Make Jobs useless ?

[Neonii]

I was more speaking of events and Content geared towards collecting Atma and cool gear ect. On my server even Pick-Up groups will rarely invite a SMN to any NM type group. And as for unwritten rules has consideration been given to the fact that they create the very folks who don't know their job often complained about? By accepting only particular jobs newer folks may feel compelled to go level those very jobs with out the time and support needed to really master a job. Maybe it would be better to welcome all jobs and allow players to put their best job forward. For example, I am a very inexperienced white mage but I can hold my own with any summoner requirements.
