Yeah, I'm also having problems landing the command grab. Is anyone having issues with his BnB -> DC command grab whiffing? I'll do cr.B, cr.A, f+A, qcb+K, DC grab and at times the grab portion just completely misses. I think it's because I started the cr.B from a bit too far away. My question is, what are my alternatives if I'm not at point blank when I start the combo?
That BNB is pretty easy. What I've found(sure others have too) you can just do qcb+LK>hcf+P. Like one motion. It's easy as hell to DC in this game. You could mash it if you want. And yeah that BNB requires you to be pretty close. If you're too far away to land a full low hit BNB, meaning you're at the tip of a max range cr.B, your only option is cr.B>far st.B>DM or Neomax.
At neutral, I favor his far D but I'm not decent enough with Iori yet. I may mix in some hop B/C/D. If I'm close and they're blocking I do a string into qcb+LK. Also you don't have to attack you can move foward and backward a bit by walking or hopping to try to bait an attack out to punish.
