I'm thinking of how the 214D can be charged, I'd like it to be for as long as we hold down D. But I can imagine if it's for a set time, 214D combo's are still going to be incredibly specific. I can only see it being gdlk if we manage to land your opponent in the corner with 3-4 Steins, Hold D and apply pressure (6B, SoD, 2A whatever.), You could really rape his primers and he could do shit except burst.
