I'm fairly new to the competitive scene, trying to get into it. Any advice?

When I first started, I had trouble doing small things (QCF + HP for example, I was never able to hit for some reason)

I don’t have nearly as much trouble now, but it still gives me trouble. I really can’t tell if it’s just my controller or if I’m just bad at this. I can do it much easier on the analog stick than the D-Pad, but people always tell me to use the D-Pad instead. What are your thoughts on this?

If it helps any, my primary team is usually; X-23, Dante, and Hulk
