Okay, so I took a look at about 3 matches and I noticed something I consistently have a problem with too.
You're incredibly stingy with your meter. With the changes made to K, you can't do that, you have to let it rip.
Also, off a jump in, unless you're intending to use some meter, you're intending to cross up, or you're intending for them to block, why are you doing d.B off a jump-in? You should know, as many times as you've jumped in on someone, that doing d.B into Ein Trigger (A), into second shoot won't work. You have to use EX meter to make it combo. And a lot of the time you did have the meter when you poke him. Since K' can HD bypass off a normal if the opponent is high enough, you can always go to HD mode (If you really want to) when you get that corner carry combo off.
Your opponent seemed to play a lot of grappler characters. If you're not comfortable using alternate guard, you should sniff for a reversal. The light version is a lot less punishable with the same invulnerability you need. A pro-tip against Clark is you can try to throw them on wake-up and if he did the guardpoint grab, buffer in your A or C dp to hit him out of it. Characters like Daimon and Takuma have delayed grabs they can do if they stagger them on your wake up. You can use K' Chain Drive DM to reversal it (though it's risky) because the move is throw invulnerable, you can't be thrown while doing it.
Fundamentally speaking, your ground game has to diversify. You run up and throw low B's or jump (which kind of ends your ground game). I also know how hard it is to do something different with K', trust me, but if you throw out different normals like d.A or do a short into a sweep, maybe even d.C, that makes a difference. They won't figure you out and maybe even guard cancel out of your blockstrings. Mix it up whenever you can. And work on those jump-ins! Hitting them a little too high!
You're doing okay and you're playing patient, that's good! You just have to work on capitalizing on the small windows of opportunity K' can provide for bigger damage/better positioning.
