Is it DI dependant? No? Is it just muscle memory? Yes?
Wait, are you talking about every combo in every fighting game ever, or something else? Hmmmmmmmmmm.
And Melee isn't THAT good, not good enough for me to get past its 100 percent bull ****, not adding ANY depth entry barriers like L canceling to make me spend the time needed to play the game. I can put the same effort into another game, and be in a game with greater depth and balance. At least Brawl doesn't do stupid **** to make itself hard for NO REASON. L canceling is hands down one of the worst ideas ever. Its nothing more than a button required every time you land with an attack, and becomes a required button and NOTHING MORE. There is NEVER a time when you could L cancel an attack but shouldn't. Never. It doesn't gain you anything. Its just a "landing" button and nothing more. It doesn't reduce the landing lag in reality, no, it sets a NEW landing lag base at the half cut range because you should ALWAYS be L canceling unless you are edge canceling, in which this situation would not apply.
Now excuse me while I go practice SF, Tekken, and Guilty Gear, or touch on Brawl a bit.
EDIT- Zio, that's very wrong. A lot of people CAN get predicted by Metaknight once and still live. Brawl matches take forever. Also, he doesn't have the best aerial manuverabliity by FAR, in fact, he has one of the worst, and any chain grab he has isn't worth talking about.
