Ehhhh, don’t just block jumpins by default. Sure, you don’t take damage immediatly, and yes, sometimes you do need to just block, in any particular match, sometimes you will need to just block, and if you anti-air’s aren’t working, don’t keep trying to use them, but you want to get to a point where the only time you block a jump in will be if it’s a safe jump or if he’s jumped over a fireball or a heavy attack, if it’s not one of those things, it means either you don’t know the matchup well enough, and you don’t know which anti-air to use, or you reacted too slow. The problem is that each blocked jump in gives them a free mixup every time. Street Fighter is about gaining advantage and using that to force damage, blocking Honda’s jumpins gives him control of the match and will just lead to eating Ochios.
If you can’t react, (and, yeah, I have trouble reacting fast enough to stuff Honda’s jumping mp to anti-air too) predict, and just sit there doing neutral jump HK, and try to backdash or focus backdash any jumpins that come when you aren’t currently doing nuetral jump hk, but doing that too much against a good player will end up with you in the corner, which is just as bad.
Of course, that’s probably all in the future for you, at this point, yes, you’re probably just not blocking enough :D.
