You missed a fairly obvious and pretty important one:

Viera:
Assassin + Sniper.

Assassinate
Sharpshoot
Reflex
Concentrate

This is such a ridiculously broken combination it's not even funny. Sharpshoot gives you the ability to use Beso Toxico (full weapon damage + Poison, and it negates Reflex, Strikeback, and Catch Arrows, for no MP cost). You get the Aim Equipment abilities if you really want to be sadistic. But, most importantly, you get Camouflage. The ability to turn invisible, run behind people, and use Rockseal or Last Breath. With Concentrate for boosted accuracy.

Also, there is pretty much no reason to not raise a Viera as an assassin. While other jobs may have better growth in a particular stat, it's fairly negligible, and the loss of high rounded stats and the massive speed drop is pretty noticeable.
