Poking is currently very powerful in the meta game. It's great for catching someone mashing and punishing them for it. It's why I don't spam pokes, I poke once and then go for my best mid starting string. Most people don't react in time to block it, they're still trying to mash out their string/d1 spree.
As for the neutral. I like occasionally "dancing". Pacing back and forth waiting to react to what they do. Baiting out attacks with nothing but movement. The walk speeds in the this game for the most part are great. And though I haven't incorporated it into my game yet, I want to start dashing under crossups. I did it all the time in Injustice.
