You haven't tried a combo this hard man...you get to the part where you would even be able to morph into Mileena maybe once out of 50 tries and you mess up her combo and have to try again. Cage finishes it off nicely and shadow kick is much easier than corner roll stuff.
If MK2's buffering is like UMK3's, you should be able to get the fan to come out, hold block in the air, enter back, back, release block, back, hp for the fan lift and you'll never miss it(offline). So now ded is a robot king? We're all fucked now.
Being able to do the move, buffering or not, is not the problem in doing the infinite. You have to catch them with the air fan throw on the same frame that you would hit them with the RH infinite. It resets the combo count when you hit them on that frame, even though all hits are unblockable.
