Rey is not available yet, but judging from the weapon she is holding in the picture, she is also a staff user.
So I assume she shares the same combat abilities as Mulan.
Zeb I don't know about, but he also has a staff weapon. It may work differently, since it can fire ranged blasts.
That's the thing I noticed most in 2.0, that the Disney figures would have combat mechanics from one of the non-Disney figures.
And I don't think the staff is like a lightsaber, the moves are completely different.
To me, it looks like Mulan is a heavy hitter, when you do the combos right, she swings the staff around like a two handed flurry of pain.
Who has martial arts combat?
The only one I can think of is Baymax, some of his melee animations reflect that kind of combat ability.
