Here are some great ways to develop your skill even further.
Problems with repeating the same gimmicks/patterns?
Like for instance, lets say everytime You do a D3, you like to do 2 more of them, then do a D4. Since this works for you 60-70% of the time. You keep using it. It also depends on who you're playing against.
If you're playing against random's who've had no chance to download you, your habits won't change that much because each person that fights you, all your tech/patterns are new to them. They have 1-2 rounds to learn you.
What you need is a steady partner (as well) that's better than you. Someone who adapts to you over time, even if it's slowly. this will eventually force you to mix it up if you get punished for doing D3x2, D4.
Let me go with an example of when I was playing Kung Lao.
The Jax player in my crew, almost NEVER jumps, and he plays super safe. I learned how to condition this behavior with kung lao's overheads, since he's more afraid of my low starter.
I use to only JIP anytime I jumped over someone. The sonya in my crew anti-air D1's me everytime when I met him. And now I condition him with jump kicks.
Fighting good opponents can help you break patterns because they themselves are breaking patterns you make constantly. Making the game evolve as quickly as you try to evolve with it.
If you don't evolve they don't either until you adapt.
This is in conjunciton with having a scene/going to tournaments.
If you don't have consistent good player practice that make you lose. You have no room to learn.
And understand that when you learn new tech/combo. You subconciously want to use it more than you should. So sometimes instead of doing the right move for the situation. you'll try and go for a specific combo/and/or tactic even though your opponent left no evidence of a pattern leading to that tech being useful.
You should record your matches if possible,
rewatch them....
And EVERY single hit you take,
Think about ways outside and inside the box of ways to minimize either damage, or leaving that opening.
ask why did they choose that option? how can I avoid that from happening again?
And every single time you land a hit,
How can I maximize the damage
How did this opening happen?
why didn't they defend it?
blah blah blah.
Once you get all your tools/techs down to a T. The rest is just more and more experience/study. D1 anti-airs don't just come to you. You have to fail alot, then suddenly you'll find yourself landing every single one every single time, and you aren't even thinking about it. You're thinking about what they are gonna do after you combo them off this D1.
once you can get your mind thinking about just you opponent's mind/habits. Then your patterns will start to fade because your adapting constantly.
