Thanks for checking out my video. I will answer a few of the questions you posed.I think that I found the culprit here. I tested this one for you.
The following characters get hit by Smoke's B21's second attack as it's a middle one, when blocked:
Jason
Kotal
The following characters get hit by Smoke's B21's both attacks as it's a middle one, when blocked:
Alien
The following characters don't get hit by Smoke's B21, when blocked:
Sub Zero
Kung Lao
Predator (even though he's huge)
Either Smoke has some hitboxes issues, or those characters do have hurtboxes issues against him. Usually, all of these characters when blocking should have to block the middle attacks, too. I don't see this happening to Sub Zero and such characters, thus there's a gap to them.
Why do i end the combos with f21?
2,1 and F2,1 end up doing roughly the same damage, they both are plus and give mix-up potential. The biggest benefit with F2,1 is the fact that it gives you an "invisible" mixup. The smoke coverage that F2,1 gives you allows you to pick your mix undercover. Also, F21 is juuuuuuuuuuuust plus enough to lure the opponent into a false sense of pressing buttons.
B21 hitbox issues?
Yes, definitely. The hitbox on b21 can be neutral ducked and punished by the majority of the cast and the whiff of the b21 will also prevent our beloved Tekunin from phasing away and remaining safe. b213 I have even been poked out of before between the 1 and the 3.
If you have any other questions let me know. Feel free to send me a msg on my vid or hit me up on twitter @israfel1214 I am far more active on those medias then I have been on TYM as of late.
