like i said, you don't want to be obvious with an unpredictable character. you need to know his chain followups and how they're affected based on how far the chain is extended before you pull in/what follow up you do. approaching just off of 5D~D/C or j.6D~D/C is a very high risk. you have to know things such as how your j.6D hit them and where it hit them. if it hit them on the leg/closer to the ground you have great mixup options with your follow up because j.6D~D will put you in front but j.6D~C will but you behind the opponent.
chain fakes, chain follow ups, command grabs, stance baits, hazama has so much versatility in his game that you don't want to be caught doing the same thing over and over and over.
