Class/Job Questions

[HEC]

so does that mean having an alt is basically pointless unless you want your character to be a different race, sex, or other cosmetic features?

Correct. Or other server indeed or re-do the main story quests and so on.

Should I get my arcanist to a certain level first since it is my main class?

Doesn't matter really which class or job you level in each order. There is also no "primary" or main class - the only distinction is that you've started with one which you can call primary but it has no impact on the game whatsoever and you can make "main" any of the other classes activated later (then you'll count as "main" the one with highest level rather the one you've started with but it's all just semantics anyway).
