My girlfriend taught herself this combo - is it any good? It looks really punishable but the damage is pretty darn good

Long range mid starter with huge crush/counter launch potential; f3,4 is easy to hit confirm so you can avoid punishment; full juggle so no recovery opportunities; high damage; long carry; combo ends well out of range of any safe recovery attack; would definitely wall splat from a longer distance than usual. Only problem is it ends in back turn so no safe pressure potential unless it ends with feng close to the wall. It depends on your play style but if you're instinctively aggressive, I can see this one either getting punished after a blocked or whiffed f3,4 (can't remember if this can be side stepped), or turned over after a botched follow-up. If you're cool headed, it'll serve you well I reckon.
