After toying around with some characters, Jade has firmly become my main. Very underrated and I'm beginning to unlock her true potential. She absolutely eats the likes of the "mighty" Sub Zero and Reptile for breakfast. Her forcefield and Ex shadow kick are freaking amazing. The only issues I have is it's hard to get someone off you if you have someone on top of you like Kang or Cage, apart from her shadow kick she doesn't really have a "get off me" move. Her Ex kick is full screen and has armour, despite her projectile being a bit slow you can throw low, medium and high for mind games, and her ex boomerangs are great for mixing up and extending the combo. Her staff has pretty good range and yeah, her only over head is a special and telegraphs, but her ex overhead is faster.
I find Raiden an absolute nightmare to deal with. I hate to say a character is "broke", but he is ridiculous in my opinion. Ermac and Cyrax are also difficult for her, BUT with patience they can be overcome...her forcefield is integral for dealing with them, and especially with Cyrax when he is throwing bombs + nets, one ex shadow kick sends him flying and both of you way beyond the range of his bombs.
Lil flash combo of the day: overhead-dash-launcher-dash-3,4,2. You can tag an ex shadow kick after 2, but you have to be very quick.
