A couple of updates on the QAC -
1) THERE IS LANDING LAG.
If you quick attack and full hop, you will have some landing lag at the end. Try it.
2) You can cancel this landing lag with a neutral b.
If you quick attack full hop neutral b, you will not have landing lag and you will have a projectile out. Try it as well.
3) Quick attack as an approach - not so good.
There's a limited amount of stuff you can do to a grounded, shielded person, and you're pretty vulnerable.
Not to say you shouldn't do it, but I haven't found much use for it yet. Also, my aim is kind of bad though even though my QAC is consistent, so I whiff a lot, which really ruins the surprise aspect of it.
However, its uber for dancing around the opponent and keeping them in their shield a lot, while safely pecking them with your neutral b.
4) QAC is the new taunt.
If you're b-sticking, you can c-stick up, control stick down in a very set pattern to continually QAC on the floor. Pika flashes a lot. It looks cool. You can also move around by doing the same thing, only moving the control stick sideways. Vids to be posted if anyone cares.
5) bsticking is awesome if you can live with smashing with the control stick.
I barely touch the floor anymore.
