Question about Jobs

[PureBreedHybrid]

1.Are there any combat advantages of hunter, thief, or trader? (such as bonus str or h.p. or w/e)
2.What happens when you level up your job?
3.Will taking on multiple jobs give u a disadvantage?

A thorough explanation would be appreciated, thanks

1. No. There just isnt.
2. Nothing. A higher level job does not give you any benefits, but later patches will.
3. No. But, if you want to get a really high level job (Level 3-4 hunter) you should stick to that or you will never get it.

A higher job lvl gives you more attack damage on other players in a job.
