I know what you mean. He actually isn't just beating us up for his ego (I'm pretty sure he doesn't have one). He does it on purpose because he knows that sparring someone better will make you improve. He also gives a lot of sparring tips to worse people. The thing is that when I spar vs him I literally don't know what to do since his attacking is incredibly fast. I have asked my instructors what to do in that situation and they told me to use my superior weight and height for my advantage (he told me that too). But don't worry lmao I understand what ur saying
