Honestly, I thought that the reason Ruby's gravity Dust bullets behave the way they do is because she herself is not using the Dust, but rather triggering the Dust by firing a bullet filled with it, similar to the act of sneezing on powdered Dust. Rather than using her Aura to actually manipulate it into doing something and giving it direction, she's just hitting it (with the gun's hammer) and causing an uncontrolled burst. So, Dust bullets just create a burst that temporarily changes the direction of gravity or something like that.

And yeah, I imagine wind Dust probably is a lot more common than gravity Dust. First, there's like you said, wind Dust is a primary type, a basic type that is mined from the ground rather than having to be created by mixing other types. Second, there's the fact that, while we have seen plenty of samples of the other various colors of Dust, we have rarely seen gravity Dust (if it is the purple Dust) by comparison. There's Ruby's gravity Dust magazine, the purple vial in Myrtenaster, and the purple vial in the clip Weiss gave Blake in No Brakes. Those are pretty much the only places we've seen gravity Dust so far. Is it rare? Why? Is it hard to create?

Weiss seems to mostly use her black glyphs to exert a "pull" force and to hold herself in mid-air, often upside down, whereas her white glyphs are majorly observed exerting a "push" force. But there is that example you gave in Round One where she causes Bolin and Nadir to float in the air above the large black glyph. If it was just pushing them, then she could've instead used a white glyph, and it would've just tossed them into the air and let them fall, similar to the glyph that threw the Arma Gigas into the air in the White Trailer.

Nitpick 1: They said Sun was on the ceiling, not the roof.

Nitpick 2: We don't know if the Dust crystal that Reese used was fire Dust, since it was bright orange, not red.

Nitpick 3: When Weiss used a black glyph on the door to trap Ironwood, she used it to exert a "pull" force on the door knob in order to keep the door shut by pulling on him. I have no idea why Ironwood decided to start slamming against it when he had previously tried to open the door by pulling on it, but... yeah.

Also, if anyone decides to check which way the door opens, I already did while studying black glyphs a little while back. When Weiss first enters the office in Remembrance, it opens outward into the hallway, and it also opens that way when Ironwood leaves the office in that same episode. However, when Weiss leaves the office in Remembrance, she is shown pulling the door shut, which means that it opened inward into the office, away from the hallway. So, since they decided to be inconsistent with which direction this door opens in, I had to check Taking Control, the episode in which Weiss uses a black glyph on the door knob. Sure enough, when Ironwood attempts to open the door, he is shown trying to pull it toward himself but can only manage to wiggle the door in its frame.
