The only real problem with how skills work in Saga is (if I remember correctly) force powers (including attacks) are skills.
So if you select Force as a trained skill for +5, and Focus in it at +5 you can start off with a force attack skill at +13 or more, targeting a defense, which is designed at 1st level to at worse work against +3 to +5 attack skills.
But then as you progress in levels skills only improve by +1/2 level while defenses go up by +level. So force users actually get progressively less likely to succeed at their powers against equal opponents.
There is nothing wrong with having characters highly skilled in their chosen careers at 1st level. It fits with the genre, fresh off the farm Luke Skywalker was flying like an X-Wing Ace.
