Jade was the most compatible female ninja (Kitana's too prissy and Mileena is a pyschopath. Tanya is just... Tanya) and her background really made a lot of people like her in UMK3 and MKD. I hope this game if she's brough back, it'd probably be through the sorcery and magic of Skarlet (I mean she was taken possession of by Skarlet, I believe).
And lets hope she's mid tier or upper mid tier this time. She started MK9 in the mid tier, she should be much better in this version. And the cosutm has to be nice, not slutty. That win pose was a mess... a litle less is more.
