Did you even listen to the Story Mode intro word-for-word? Johnny Cage stated in plain English that it was Shinnok who manipulated those events, not Quan Chi (who only acted under orders from Shinnok), so either you're wrong about who the manipulator was, or Johnny Cage (a canon survivor of those events) was lying.
Shinnok was unplayable in MK9, so my point still stands.
If you really want to compare the Liu Kang and Kitana cameos at the end of MKX to Shinnok's MK9 ending cameo, as far as importance goes, then my point still stands.
If Shinnok who only had a cameo at the end of MK9 was unplayable, then by that same mentality Liu Kang and Kitana should have been unplayable in MKX.
You have a double standard, though.
Kitana is your favorite, though, so the mere mention of me disagreeing with her inclusion makes you sour.
