Personally, I'm all for keeping the psycho feats back in the Far Flung Fantasy section. But if you do the math a 10th level Jedi Guardian/10th level Jedi Weapon Master should have four attacks, plus two if they get improved two weapon fighting, plus that extra one. Throw in Heroic Surge, and BAM! 8 attacks a round! Just like a Grand Master using old D&D rules! Only doing a hell of a lot more damage!
