Questions about star wars saga

[Kiero]

Is me or is there some inbuilt safeguard to stop players abusing the 'all of your skills at level 1' policy by taking, say, scoundrel/noble at level 1 and then soldier/jedi for the remaining levels?

What's abusive about it? It's a tradeoff plain and simple. A little combat juice at the start for a lot more versatility outside of combat in the long run.

And the options are Scout or Noble, Scoundrel isn't as good. I went Scout/Jedi in the SE game we played. Just as good as the pure Jedi in melee (though a little weaker in powers), much more useful outside of combat.
