When the combo ends, you have to block correctly and then pushblock them to gain some space back.
With the space you create you gotta use that well, which will take lots of practice.
Obviously if you have no idea what you're doing you may lose that space right away, but practice makes perfect.
Also I made this video which might help you understand things a bit better.
Specifically in regards to resets vs combos, which a lot of new player overlook at first!
So happy I can finally post this in a thread.
Oh I remember you too, we just played, I was the Painwheel with Cerecopter
