... lmao. I joined that room, saw that match till the middle and got kicked out. Oh well.
ok so I'm not sure if you were just trying to troll with Hazama in that match or actually trying to play him. So I'm assuming you were trying to play him correctly. I'm only going to tell you what you're doing wrong and what you're not doing so well in so my apologies if it sounds harsh.
Here we go. Don't just stance in neutral and wait for him to hit you for CH. His DP is nice as an anti air but never get predictable with it and don't spam it on wakeup and definitely do not depend on it as a DP. It's just a bad DP. Don't just run up 3C someone, instead, do a little pressure here and there. I mean you're not just gonna get a 3C on someone when they default block to low. Don't do 3C > Ressenga like... ever. That's the worst option you have after 3C. Make 3C safe with Jabaki instead and only do 3C > Ressenga when it is completely random. Another thing was your muscle memory. You dropped hit confirms in the air because you just defaulted 5B > 3C. Wake up Houtenjin is a no-no. Your chain approaches are far too predictable. Use different chain followups and alternate between letting go of the chain sooner or faster to make it less predictable. You can also bait anti airs by cancelling your chain in with another chain if you have the stocks. Throwing out a Mizuchi at neutral with only 50% meter is a very serious no-no. And at last, the final thing that wasn't right in your gameplay was combos. You need to learn combos. A lot of the combos you did were right out of CS1 but that's understandable if you haven't played him for that long. But if you are serious about learning this character, learning his combos is the first step.
