My aim goes all over the place when I try to spray standing up. I don't know if it's placebo but when crouching it seems I get more hits, it's worth it trading accuracy over vulnerability ?

In a Spike Rush game, all characters are supposed to have all abilities except the Ult. But Astra seems to have only 2 stars instead of 5. Is this an actual omission or a small error? Hopefully gets fixed soon.
