yep, bro, you're right here, from the 3 Mileena's moves showed on that KK, only Teleport Kick in fact, is Mileena signature move since MK2 ... the other 2, are bullshit that NRS invented to put in the game, and in Kitana moveset, only to mock the Mileena's absence situation.
Yeah, it's possible to revamp and redesign Mileena , in order to her have other special moves replacing the teleport kick, and even not giving sais to her this time, kinda more or less what they did with Li Mei, that at first, had Sais, and next games, they took that from her .... they could go in this direction, and make Mileena without sais , and giving her other temporary weapon in MK11 .... maybe Kamas ?
anyway, it's clear to me, that NRS and Ed Boon will not bat an eye, and will not make any effort to have Mileena in this game .... they already hint to extreme that she is out, and, Mileena fans that are mature and rational, just accepted that .... so, IMO, as a huge passionate fan of Mileena, she is out, and only in the next game (Mk12) we will see if she will return or not, so, IMO, this KP 1 leak is fake as hell .... only Sindel make sense to be here as DLC .... Takeda ? nahhh nope, very low tiny chances, he doesn't have a monstrous big fanbase to justify his return ....
