I'm going to spell this out so other people don't get confused by your madness.
You cannot REVERSAL poke. Do you not know what that means?
Jax's d1 has a 7f startup and is -3 on block. That means if they're not reversal poking, its highly likely that a second d1 after you recover from the first one will connect. We've now established a pseudo 50/50 situation where the opponent has to guess between d1, d1 or d1xxdbf1.
They cannot reversal poke, so they will get beaten if they mash. If they don't mash, then they're probably reading the dbf1, so a better player will now (post bug fix) d2 KB, or neutral duck into full combo. D2s are often even slower than d1s, so that makes d1, d1 even more legit. Baraka has a 10f d2, one of the best in the game, and he has to be within 1 frame to not get beaten or trade with your d1. If they start neutral ducking, you can hit them with f3, which they'll likely block, but now you get to stagger.
All of this is very much paper/theory fighting, but we've seen time and time again that command grabs are always even better in practice than on paper. Turns out, people like to block. That's we see so many more pros holding block and reacting to throws with a tech so much more often than harding reading and d2 KBing or neutral ducking.
