Except it’s not a “free way in” any more than Sakura’s LK tatsu or Dan’s LK Danku or Makoto’s IA Tsurugi or Adon’s IA Jaguar Kick or Sagat’s EX Tiger Knee or tons of other moves that are either -1F 0F or + on block (and ALL of them have more active frames than Cody’s F+HK meaning they can be even more + on block and many of them break armor.
No you wont unless it was a sweep or you did the F+Hk very early. I just explained that. F+HK = 29F total. Most mids are 20-25F. That is a big part of why the Evil Ryu matchup is tough. His crMK is 26F, outranges most of Cody’s anti low normals and his walk speed is better and his damage is better. Often times doing a F+HK to get over an expected crMK results in you getting counterhit by Evil Ryu’s 3F crLP after you hop over the low or getting baited and eating a premptive crLP/crMP when you expected crMK
If F+HK hit crouching you’d be able to get the opponent into a better position much quicker. Namely: In the corner.
Unless they make F+HK airborne like 5F until fully recovered then you’ll still be very susceptible to focus crumples or getting counterhit when trying to go for a crLP after a whiffed F+HK.
Or an EX Ruffian - EX Criminal Upper or an EX Criminal upper raw followup or a F+MP reset or just a jump in crossup or not situation after a quick rise.
They have no reason to worry about trying to do a crLK or crLP when respecting F+HK. As a matter of fact those moves specifically BEAT F+HK. 95% of character’s crLP will hit Cody during the F+HK and the crLK will always recover well before Cody does. Even the slowest crLKs are about HALF the frame count of F+HK.
As a matter of fact, the threat of eating ~200 damage for throwing out a crLK/crLP at the wrong time would INCREASE their respecting of that move. Good players REGULARLY do crLP during footsies vs Cody at mid range specifically to stop his F+HK because crLP is literally a 100% hard counter with ZERO risk because it can’t ever be hit by F+HK.
But that is the exact issue. It’s a gimmicky gamble. You are taking a unneeded risk for a MAYBE. Guarantees almost always trump maybes. That is why you so rarely see Seth win tournaments. A low risk mid reward character like Akuma is far better than a high risk high reward character like Seth because CONSISTENCY pays off more in long sets and in varied match ups.
For F+HK to work how you want it to, you need to be doing it ~10F BEFORE the opponent does anything. Meaning you are making a guess. If they do NOTHING however that guess results you in gaining nothing and being in a situation where you are now betting that the opponents reactions aren’t fast enough and they wont tech your throw or hit their crLP/crLK before you go for a crLP to frame trap.
Regularly betting against another persons reactions at high level results you losing more than winning. Again, more gambling and inconsistencies added to your gameplan.
I do appreciate you at least giving an argument beyond “fairness” and trying to present a REASON.
