My big change would be to release more materials simultaneously with the core rulebook. Even if you like/hate the game system, having a virgin chunk of SW universe to play it in would go a long way toward having characters make a difference in the universe, aka preventing Forgotten Realms Syndrome.
A system based on SW relies on content: if you have to make up too much of your own, it can easily unbalance the game. Whereas in DnD things like regular longswords could pretty much be believed to be mostly the same, it's not the same with droids, ships, or even blaster pistols.
I'd agree with nerfing Force users, except for a gigantic disadvantage: opposing Force users. For example, "I detect a disturbance in the Force" is all it takes sometimes to ferret out your secret mission to the Outer Rim.
I noticed this in the twin IC SW games in Gaming Action|Playing the Game. Maybe this is the same with Paladins in DnD to a lesser extent, and maybe also Luke never got the jump on anybody yet persevered, but I think Force users are playable as is, given the right content and context.
Which brings me back to my main complaint: how do we know what IS the right content and context if they don't release very much?
That being said, I'd like more chances to either play or create something for the system before I can recommend rules revisions to it with any seriousness.
