Generally speaking, we should try to avoid crows in order to survive. But you can also use it. For example, if you know that a teammate is not skilled, you can save him with crows, windows and door panels. For example, your teammates are finally out of the supervision field of vision, but they are still being chased. You are not far from the supervision, you can deliberately startle the snake, turn over the window and so on. Give supervision a critical point.
Of course, sometimes it will roll over.
As for the big shots, I don't watch live broadcasts very much, and I don't know much about them.
