Personally i thought the lightsaber thing was way cool.

Also i personally wanted to turn it off thp after my first 3 matches with it on and one run of the arcade quest. Why? Not the light show. The sound effects messed up my rythm. I was actually really surprised by this but its true. The changing of the sound effects totally made me respond incorrectly multiple time. Especially the sound on block.

Its a cool feature. But we should have had the option to turn it off for us personally.
