I’d watch pros first to see how they specifically play the agents you’re interested in, because not every scan is played the same. Also, if you’re solo queuing, you kind of have to set up plays yourself and clearly voice what you’re doing. I find that asking, “Do you want to do something?” doesn’t work as well as just saying, “I can do X, so peek or play off this.”. Id also make how you communicate be efficient, you dont see long winded explanations even when you watch pro play.
In clutch or intense rounds, making people think about whether they want a piece of utility (yes or no) and then communicate that takes too long. It’s usually better to just say, “Hey, I’m doing X,” and let them decide how they want to react to it.
Being vocal about how you’re using your utility is probably the most important thing, in my opinion. If you want to do something, communicate it. If you want your team to move or path a certain way, communicate that with your utility.
