Bleys is right. The first subjob doesn't matter much, if you're going for advanced sub job and not gonna use that subjob afterwards.

My example:

I wanted Thf/ninja. I "had" to level my warrior sub job before my thief was level 30.

Guess what? I stopped leveling my warrior after it hit level 8. Why? Simply put: waste of time. No one ever complained to me of my low warrior sub. Everything I needed was provoke. I got parties just as well as anyone else, I really see no problem before level 30. It really would've been waste of time to level my warrior to something like level 20, as I never use it after I got my ninja.

Time is money in this game, and don't waste it in something you don't need. Use it more wisely.
