Yeah its very dangerous. But beside some CA move the CE is the only good anti step move of her. Maybe 66A is also good.. ^^ Btw nice german nickname, haha :D
Well forward movement is safe, while backstep and sidestep is unsafe. You can always cancel one step into another one (like sidestep into backstep for example). So when you see the flash, you just mash 6666666 and G and it cancels your Side/Backstep into a frontstep. Which means you can block the CE.
