AAs - Scorpion doesn't have nice anti airs and even if he did, I'd still fuck them up. I'm getting better at this when I notice I got somebody in the corner or somebody cornered himself with a combo, because it's easier to anticipate.
B2/F3/F4 xx Hellport cancel confirms - Deadly tools Scorpion has that I do not utilize at all.
Dropping combos off anti airs and j3s on crouching opponents - Fucking hate that as I leave so much damage on the table even if I do delayed f3 meaties to specifically catch wakeup jumpers.
Punishing throw attemps with standing 11 - I never get anything other than d2 when reading a throw.
Hit-confirming d1/d3 into s11/s21 - When I hit a poke I usually just do shit instead of confirming into jailing buttons.
Various fuzzy guards against Erron/Geras/Jade - I'm free to Erron's 212121/b222 slide cancels, Geras' 111 and Jade's OH into OH or OH into low projectile cancels and shit like Cassie's and Sonya's OH strings, the latter being even more embarrassing.
I bet there's a whole lot more that I can't think of right now. I've started playing only 10 matches against people in casuals so I can save all the replays of my losses afterwards and check out where I got hit and why and where I fucked up specifically, and make notes of stuff to lab.
I'm thinking about making a matchup sheet for Scorpion where I write down everything including frame data, hit levels and cancels windows for every character along with punishable wakeup U3s and ranges where I want to stand to have a shot at whiff punishing them. Hope that helps a bit as I'm saving to go to Viennality next year and I want to at least win 1 pools match.
