It's definitely a strategy that works, it makes reads a little easier because it definitely limits their options. Over the past week or so, I've definitely had this be the difference between a W and an L. Granted almost all of this has been online, but even offline my main training partner had trouble dealing with it.I dig it. Gonna try it at my local this weekend. I'm already a 21 whore so this will make it extremely annoying.
The thing is: When this is coming at you, your natural response is to want to move. It's hard to fight the urge. It gets to the point that people will start trying to punish telekick too early and get hit by the sai (assuming they don't use the OP forward walk tech). I've caught a few guys with f3 because once they realize they shouldn't move and should block low, they sometimes get paralyzed and just don't react fast enough.
Having this as another combo ender/mixup is only a good thing. I feel that we (as Mileena players) could honestly get a lot out of EX throws as well. We could use our normal damage combos and the EX throw ender to get pretty much this same setup for a bar.
If we never let the opponent know what Mileena will do next, she WILL win. Frustrate them into respecting the options and you can run mad free. We just have to make adjustments and mixup faster than other characters in the game.
