Summoner Info

[Lemonaid]

Is there any benefit to not using the jobs? In other words, are there situations where and arcanist is better than a summoner or a scholar? Are there reasons why I would NOT choose a job?

Jobs are more like a proficiency class, so u can say that classes are pretty general and can be used while solo, so u have more skills to add, Jobs are meant to fill a specific Role, so you'll want to change to them on group play.
