Stuck with Lei

So i jump online, and get to 3rd dan w/ 50% w/l, and now it's obvious i've hit a wall, because i just went ~1/20 and am a 2nd Dan again.

What should i work on in general? I don't have a tried and true plan yet so i'm up for anything.

 

The first step to improving is knowing why you lose. Depends on what you rely on win from an offensive and defensive standpoint.

At 3Dan, you're probably taking more damage than what is necessary.
-Techrolling and QuickRise is what you need to start learn
Many combos can be avoided or reduced in damage if you learn how to avoid damage by getting off the floor.
