DPs (as well as quarter circle back) are easily my most consistent input. Hell, they seem to come out even when I don't mean to do them. I'm sitting here, in KOF, trying to fireball, the opponent jumps, and it's like the game knew more than me that I needed a DP. And so DP came out. And I was like I am the best player in the world.
You know what input I can mash better than DP though?
You'll probably never guess.
