I have no beef with a sorcerer with a laser sword being flatly superior to Bob on the street. They have space magic and laser swords, duh. It gets more prickly when in a game if they're outclassing the other PCs to a big degree, however, and I think Fantasy Flight did an excellent job with it. The Force is strong, the Jedi talents are good, and lightsabers are absolutely horrifyingly lethal, with easy crits and basically ignoring armor and toughness to do direct health damage. But a non-Jedi with the same XP to spend will have bought more skill ranks and equivalently good talents, and other weapons are also extremely deadly with a high skill and some mods attached. It's not hard to wind up with a blaster that's essentially the one from Rogue One with the backpack power supply and proceed to mow down anything in sight. The fact that FFG's system makes you buy everything with XP is an inherent balance to the system, 'cause the points spent on force powers have to come from somewhere else.
