Honestly guys I think Mileena needs a buff. I've been a Mileena main since MK2 and in this game she can not open people as easy as everyone else. It seems really hard to get damage with her because you can practically just low block her. This leaves you with two options. MB roll or f3. One is practical at high level, the other isn't. The problem is the one that is practical needs meter. I think she needs a couple of things. A faster overhead. Maybe her u4 like the coombo ender 2,1,u4 as a stand alone move. It does not need to pop up like MK9. It can have the same properties and just be a faster overhead than f3 with an un-techable knockdown. Scorpion has this. Scorpion also has a much faster overhead opener than mileena's f3. Mileena's advantage is a confirmable overhead, but 32 frames is ridiculous. Making her roll low will only change her slightly as I said just block low to begin with but at least two more strings have a mix up. Last but not least maybe make f4,4 cancellable into air sai just for more damage options. Give me one at a time to make sure she can be balanced, starting with a faster overhead option. Other characters just have more options and damage without a Y.O.L.O. play style. She wasn't great in MK9 (lower mid to mid), but I think she was better than she is now.
PS she also needs her MB ethreal TP's to actually do something different allow her to dash cancel them and give them armor to hits and throws and make them slightly faster. Another option I thought of is make her f1,2 overhead. She just needs something other than MB roll and a 32 frame f3 to make people respect defense and stand to block. My final option is keep everything the same and allow u4 in 2,1u4 to pop up like u4 did in mk9.
