So the counter to people blindly mashing d1 pokes is to blindly mash out your 1f link jailing high string on hit or block after you d1 poke? Sounds totally in favor of the person trying to play with some modicum of skill.
You can also walkback and punish with F2~db4 which sends them back to fullscreen while you're plus
You can also walk back and punish with f43 which its +15 on hit and they have to take a 50-50 with throw, low or a jailing high
You can also short hop and punish
You can also B3 after d1 hits
You can also slightly step back and B1, 2 for a KB activation on whiff punish
You can also throw
You can also cancel your d1 into db1 so when they mash you gain 95 health back
You can also do D1~db4 and hit them because they are mashing
You can also Double d1 to force them to respect your D1
You can also walkback and hit them with the longest reaching low in the game as you walk back
You can also, ask nicely and stop being on the side of the modicum skill for once.
