Eh well. I didn't expect them to have a set bonus or anything, but it would've been cool.
Now that I have the lightsaber damage upgrade, I'm upgrading my saber to orange. Honestly, haven't noticed much change in the output, though. Some enemies that took three normal hits before still take three, and those hopped-up psychos on Dathomir are about the same, too. The skill tree sold me a lemon.
