I don't see how there's nothing to be discussed. I came across four unanswered question just by playing a bit in this weekend's tournament :
1) Let's look at the different places where we can jab somebody and see if it alters the comboes we can land. Example : if we jab somebody who ledgehopped, is dsmash stagespike guaranteed and on which stage ? If we jab somebody on a platform, is platform drop to fair guaranteed ? If we jab somebody on a slope, downwards or upwards, how does it affect our frame advantage ? If we jab somebody on a moving structure, what can and cannot be done ?
2) Let's look at the different moves we do not need a powershield to punish and how should we do it, because a normal shield is much more reliable. Example : turn around shield to usmash oos works against most dash attacks. And how do we punish these supposedly spammable moves like marth's fair and falco's phantom if we need to, in case our opponent thinks he can win just by being lame ?
3) The matchups that make or break luigi : diddy, olimar, ICs, Snake, Falco, Marth, MK, DDD, Lucario, ZSS, Pikachu. We have to study them because most of the stuff we know about them is 'offstage, the edgeguarder wins. Onstage, they win if they camp'. And I'm pretty sure there is something else to it.
4) There are a couple moves I do not see myself using that much : dtilt or dash attack on the ledge, upair's back hitbox, downwards angled ftilt, etc... And the main reason is that I'm not really sure about what can be done with them. In example, I'm fully aware that if I wanna bair somebody below 30%, I have to full hop it or do it while falling because if I short hop it I'm punishable on hit. But down angled ftilt ? I do not know sheet about this move.
