The biggest thing she did was a jedi mindtrick on a mind control susceptible soldier on the 3rd try.
You're acting like she went all Force Unleashed and took down a Star Destroyer with the force and then force lightninged Kylo to death.
She didn't even know Jedi and the Force was a real thing until like 20 minutes earlier. Then suddenly she knows she can mind trick people, it doesn't make sense for her to even think to try it. Piloting and basic saber fights you can argue she's just going with her instincts guided by the force and I'm ok with that.
This seems more like the Force is some sentient being helping her out or using her as a puppet. Which is maybe what they are angling for, who knows.
