A staff and a sword are far too different for skills to transfer. You go try using a sword like how you use a staff and see how effective it is. Training with a staff only gets you better at weapons like a staff. A sword is not like a staff at all. Especially a lightsaber. We also don't even know how much training she actually had with her staff. We barely saw her using it. She lived on a pretty empty desert planet. Jakku wasn't like Tatooine. Tatooine at least had heavily populated areas full of thug like people and mercenaries. Not to mention the Tusken Raiders out in the sands. Jakku appeared to just be a mostly empty sand pit that was just a battleground for the Empire in the past so scavengers set up there to make profit. I can't imagine there is too much for Rey to fight there so we can't really assume she is even a master at using a staff.

Back to the main point, skills with a staff only transfer to staff-like weapons like spears. It would essentially being like being saying just because you can drive a car, then you can operate a tank. The car and tank are very different. Too different for skills with either to be transferred. Go pick up a big stick outside about the size of a staff and trying using it like you would a sword. I can almost guarantee that one half will end up hitting you. Then go pick up a smaller stick about the size of a sword and try using it like a staff. You will be limiting what you can do with the sword. A sword is a versatile weapon. You can swap hands with it and flail it around without much restriction. A staff is fairly restricted in how you can use it.

The reason I'm trying to emphasize how different they are is simple. Before you say something like "well, I'm not going to use the sword like a staff. I'm going to use it like a sword". The thing about that is that you only know how to use a staff. Your combat style revolves around a staff like weapon. A sword is not a staff like weapon so your skills can't transfer easily. You'd be going in just flailing the sword not knowing how to use your staff skills(because you can't use a sword like a staff).

Does this help you see what we are saying?

This. Please let Rey eventually use the double bladed light saber like Darth Maul's. It'd fit in perfectly with the combat style that Abrams set her up for, and it'd be nice to see the return of that style of light sabre

If you're very skilled with a staff and cant adapt to using a sword-type weapon relatively easily then you may be retarded.

are you trying to say that having the ability to use one thing does not give you some skills at using something very similar? are you one of those people who was never athletic or coordinated and able to apply certain skills elsewhere? I never said anything about being a master, but being able to hold your own against a skilled person who is badly injured? I think anyone with any sense of using handheld weapons could do it.

They are not the same, but they are definitely similar. it's like people who are natural athletes. they tend to be good at just about any sport they pick up.

They are very different. but when it comes to being generally skilled with a staff, you have to admit that it puts you at a very good predisposition to be comfortable with using a sword.

...have you seen the movie? Rey is very much skilled with a staff. and I understand that an amateur swordsman is nothing compared to master, but you are definitely blowing way out of proportion the difficulty of using a sword effectively. anyone with a good sense of hand-eye coordination could catch on pretty easily. Lets not forget that Rey was a very agile and able bodied person fighting a master who has been terribly injured. It's not that far fetched that rey was able to do what she did.

lmao calling what I'm saying a far fetched theory. I'd call it common sense but you do you man
