Its horrible dude. Besides the fact that you cant cancel it on start up like you would Sindel, there are no real options besides an unsafe teleport on block, and airblast which gives you almost no meter for a single one. Nobody is going to stay on the other side of the screen and say, "Oh shit he's flying! I CANT GET CLOSE." Whats going to happen here is they are most likely going to approach you and punish you.Thing is... 312 in to EDU has options. It might not be the best strategy but its a way to bait a TKP, build meter and or airblast.
When your opponents safest option is to "Block & Punish" what you are doing. Its not good.
