You'll get back in the groove of things pretty quick, I'm sure. Just try to fight REAL players. Fighting randoms will just get you back into bad habits, at least in my experience.
I'll be fighting my friends soon enough. I'm playing randoms right now to try to remember how to react to situations. I saved my last fight where I was getting wrecked by scrubbiness and then started adapting to it. The finish I used on the guy was glorious and I hope he realized why it all stopped working.
