This is EXACTLY how I feel, and almost the exact same thing happened to me. He was fighting Arakune copperdabit(spelling?) and I play Arakune A LOT so I knew about the full curse setup after air grab, but he just completely ignored me when I told him he needed to burst at such and such point to avoid the curse. Yes I know I can't beat you, I know I have a lot to work on, but still...
Wait I listen to advice, what are you talking about. I try my best to become good. What advice did I not follow. I even play online more.
