Able to be every class?

[Duuude007]

I've heard it said that you can experience every class (eventually) on a single character.

Is there truth to this, or do stat allocations (don't know how those work) mean its pointless to try a magic class after being a physical class, or visa versa?

Yes it is true. Also, stat allocations can be changed by spending 10k Grand company seals.

The only jobs (so far) which have a true need to reallocate in order to reach their full potential are SCH (MND stat) and SMN (INT stat), both of which derive from the Arcanist class.
