Jab has such great mindgame potential, I do literally everything after it now. Besides the obvious stuff (jab to dsmash, jab to grab, etc.), there's:
Jab to spotdodge...
Jab to charged fsmash (in the other direction sometimes)...
Jab to SHdair...
A lot of it is character/player/percentage dependent tho. I'll jab to spotdodge a lot more vs DK/Marth/MK than vs like...Samus or Sonic since they're less likely to mash out something punishable between jab cancels.
When I'm BEING jabbed, I either mash nair, upB, or just hold shield if I think they're going to try to cancel it into something. If I'm feeling ballsy, I'll try dsmash.
@Exdia: What do you mean when you're in a jab situation? Jabbing or being jabbed? Explain, thanks
ME: good this is good more data for the ultimate battle its not when i ask questions im asking cause i dont know(i played mario from the start)i ask to see where everyone is because right now the boards are stuck but im going to fix that just a matter of time so lets just focus on more info and more characters.
@Matador: May you explain what you followup jab, how you followup after jabbing (any) & why you're doing what you're doing. Helps gamer get a much better understanding & helps them think about those situations from a better perspective. I don't mean to come off as dictating (condescending etc) but that's how I feel when I read your post (rarely my own believe it or not). Usually, (even with myself) before I post I'll re-read it as if I were the reader & ask myself multiple questions in order to confirm that it's understandable.
Mashing versus timing may be the next topic I'd like to discuss. Good chance it will be
ME: nah matador's answer was correct "Just what i needed" says mario omari i need an answer from you and all others.
EVERYTHING WILL COME TOGETHER JUST YOU ALL WAIT....
