I don't know if you'll be able to hear me all the way up on your high horse as you are, but if you'd deign to come down Moral Highground Mountain to hear me out, it's really easy to beat them.
If you have Qui-Gon Jin, beat up on Rey until the Guard taunts, then break his taunt with Qui-Gon and continue to whale on Rey.
I don't have Qui-Gon. Instead, I have Old Daka and Royal Guard. I use one (or both, if she resists) to stun her, then just beat the hell out of the Guard first.
How do you deal with her Foresight? Simple--throw an attack at her and eat it. Think about what's most annoying about being dodged: It's that you probably wasted a powerful attack because the dodge was random. Attacking Rey, you KNOW when it's going to happen, so you just waste a basic attack then blast her. Easy.
