it would need to be tweaked so you couldn't have a double bladed saber used along with a single bladed saber or rifles with pistols.
Well if you use a 2-handed weapon in main then the offhand would be restricted to everything except generators/shieldsfocuses like it is now. You could only dual wield 1 handed weapons. Otherwise you would start seeing troopers / smugglers/ bounty hunters/ agents dual wielding assault cannons and using invisible chest armor, pretending to be some sort of space-Rambo
Before this I'd like to see them remove the "requires X type of weapon" restrictions on some abilities.
And yes it's silly how Knights and Warriors can't jump without their Lightsabers xD.
