Nightmare is really powerful, he have good tools, but he is not broken or something. You can easily win against him if you know the character and how he moves.

I don't mind him. Now that I am more comfortable fighting him, it's more of a mind game and mix up thing than anything else. Stepping/evading for a preemptive strike helps too.

I actually really like playing Nightmare over any other char since I main siegfried, I always get the most epic matches vs Nightmare! =3 one of my favorite players to play on Xbox is Chrono Orosko one of the best NM players I ever saw..
