Nothing like running on slippery rocks with your eyes closed and a lit light saber to increase your force sensitivity. (well it's either that or death.)
Rey should really put that lightsaber on her staff. Would be much more awesome IMO since she can already handle that staff really well.
Didn't you put that on the Star Wars vs Star Trek post as well? I'm sure Captain Picard posted a picture of himself doing a facepalm to that. Not as well as Chirrut...I'm one with the Force, the Force is with me
Yeah, they could also call them Lightsaber Naginatas if they wish. It would be something different (we haven't seen any in movies AFAIK) and cool for Rey to use.
....I still think they should give her a lightsaber-naginata since she is obviously very good with her signature weapon, the staff.
