ok i know u gotta be lvl 30 to be ninja.
and am make a nin/war, should i take the war to 30 then take main job nin sub war.
so what i wanna know is if the warrior really should be lvl 30 when it is sub, or is it better to lvl up with another job like thief, whm blm bla bla anything

and then at 30 switch to main nin sub war so they both lvl 1 and then example just take war to lvl 10 then rest on nin?
thanks!
